Assassination of John F. Kennedy

The Assassination of John F. Kennedy, is the event in which John Fitzgerald Kennedy, President of the United States of America, was killed on November 22, 1963, during an armed attack while riding in an open-top car as part of an official motorcade through the city of Dallas, Texas. The 1961 model Lincoln Continental limousine carrying the president was fired upon as it passed through Dealey Plaza in downtown Dallas; severely wounded, Kennedy was quickly transported to Parkland Memorial Hospital, where despite all medical efforts he died at the age of 46. Immediately after the incident, official statements indicated that the assassination was carried out by gunfire from the sixth floor of the Texas School Book Depository building, which became the focal point of the investigation.

The assassination of Kennedy was not merely the killing of a president but also a turning point that affected the political stability and public trust in American institutions during one of the tensest periods of the Cold War. Occurring just one year after the Cuban Missile Crisis, the event took place in a context marked by intensifying nuclear deterrence, intelligence operations, and ideological conflict; Kennedy’s death while in office generated widespread impact both within the United States and globally. This assassination, occurring at the end of a relatively short presidency, fostered the perception of a “half-finished political project” and has since become one of the symbolic ruptures in American history embedded in collective memory.

From the moment it occurred, the assassination became the subject of numerous investigations, official reports, forensic examinations, and public debates. The identification of Lee Harvey Oswald as the perpetrator, his murder by Jack Ruby just two days later, and the contradictions emerging during the investigation created a lasting arena of controversy. On one side, the official narrative maintained that the president was killed by a single shooter and that no conclusive evidence of a conspiracy existed; on the other, conspiracy theories emerged centered on the Mafia, intelligence agencies, foreign states, domestic political interest groups, and structures akin to a “deep state.” This tension has transformed the Kennedy assassination into one of the most studied cases in modern history, where evidence, testimonies, and official documents are continuously re-examined, and political events are deeply intertwined with social perception.

Over the decades, documents released, congressional committees conducted, and comprehensive investigative works published have diversified both the factual aspects of the assassination and the interpretations surrounding them. The Kennedy assassination has thus become a fundamental reference point not only for understanding the United States’ domestic and foreign policy in the 1960s but also for examining state-society relations, the limits of official investigations, the rise of conspiracy culture, and the ways modern historiography deals with uncertainty.

The assassination of Kennedy occurred during one of the tensest phases of the bipolar international system established after World War II. John F. Kennedy, who assumed office after defeating Republican candidate Richard Nixon in the 1960 presidential election, operated within an environment defined by the “Cold War competition.” The nuclear arms race, ideological and geopolitical rivalry with the Soviet Union, proxy wars in Third World countries, and the fragility of European security architecture formed the core elements of Kennedy’s foreign policy agenda.

Kennedy’s domestic priorities included sustaining economic growth, strengthening social policies under the banner of the “New Frontier,” and expanding civil rights for African Americans. Steps taken in the field of civil rights clashed with discriminatory practices in southern states, creating tensions between federal and local governments. The federal government’s occasional direct intervention against racial discrimination increased discontent among certain political and social circles in the South, becoming one dimension of the political polarization of the era.

In foreign policy, the Kennedy administration soon faced serious crises. The failed Bay of Pigs invasion in April 1961, aimed at overthrowing Fidel Castro’s regime in Cuba, damaged U.S. prestige vis-à-vis Cuba and negatively affected relations between the Central Intelligence Agency (CIA) and the White House. Rising pressure over Berlin in the summer of 1961 pushed the United States and the Soviet Union toward a new line of tension in Europe; finally, the Cuban Missile Crisis in October 1962 brought the two superpowers to the brink of nuclear war. The resolution of the crisis, involving the withdrawal of Soviet missiles from Cuba and the U.S. agreement to remove some of its missiles from Türkiye, averted the threat of nuclear war, but the management of the crisis generated differing reactions both within the United States and among its allies.

U.S. policy toward Vietnam also gained increasing importance during Kennedy’s tenure. Since the mid-1950s, the United States had provided military and economic support to South Vietnam; the Kennedy administration, while avoiding direct deployment of combat units, significantly increased the American presence in Vietnam under the guise of “advisors.” The goal of preventing the spread of communism in Southeast Asia served as a key source of legitimacy both in Congress and among military circles; however, the deepening of the Vietnam War in subsequent years led to retrospective debates about decisions made during Kennedy’s presidency.

All these developments transformed Kennedy’s brief tenure into a period marked by intense crises and rapid decision-making. Initiatives such as negotiations on nuclear weapons control and the Partial Nuclear Test Ban Treaty, alongside efforts to gain superiority over the Soviet Union in the space race, reflected both the administration’s search for “détente” and its aggressive moves to escalate competition. This context laid the groundwork for the perception of Kennedy’s assassination not merely as an internal security incident but as a political murder with global implications.

During Kennedy’s presidency, the U.S. security architecture was shaped by a network of institutions with complex interrelationships. The CIA, the Federal Bureau of Investigation (FBI), the Secret Service, the Joint Chiefs of Staff, and the defense bureaucracy played central roles in implementing foreign policy decisions as well as in domestic security and intelligence operations. Following the failure of the Bay of Pigs invasion, changes in senior CIA leadership rendered the agency’s position vis-à-vis the White House controversial; criticisms regarding the preparation and presentation of certain decisions contributed to growing institutional mistrust.

The FBI held a prominent position during this period in both domestic security and political surveillance. The long tenure and decisive influence of Director J. Edgar Hoover placed the FBI in a privileged position within the federal system. Hoover’s approach to combating communism, the civil rights movement, and various political organizations did not always align with the Kennedy administration’s priorities; nevertheless, the FBI became one of the principal actors in the investigation following the assassination.

The Secret Service, responsible for the president’s protection, was an institution expanding its mandate and facing growing public attention during Kennedy’s term. Open-top motorcades, large public gatherings, and an intensive travel schedule increased the risks to presidential security; conversely, the extent to which protective protocols adapted to the evolving threat environment became a subject of intense debate after the assassination. The military and defense bureaucracy maintained a close but occasionally contentious relationship with the administration, particularly regarding nuclear doctrine, troop deployments in Europe, and Southeast Asia policy.

This institutional landscape defined the framework of the official investigations conducted after the assassination. The nature of the relationships between actors involved in decision-making during Kennedy’s presidency and the intelligence and security institutions became a frequently referenced element in later debates surrounding the assassination. In particular, the activities of the CIA, FBI, and Secret Service before and after the assassination have remained central to both official reports and alternative narratives.

The Dallas visit during which the assassination occurred was part of a broader Texas tour designed to strengthen internal Democratic Party balance and consolidate the voter base ahead of the 1964 presidential election. Texas, both in population and political weight, held a critical position in presidential elections. Although Kennedy had won Texas in the 1960 election, the state’s Democratic Party organization was divided by ideological and personal conflicts. Tensions between Governor John Connally, Senator Ralph Yarborough, and Texas-born Vice President Lyndon B. Johnson made it difficult to project party unity before the public.

For this reason, Kennedy’s planned Texas trip in November 1963 was designed to bring together the party’s different factions on a single platform and to establish direct contact with voters through a series of meetings, openings, and dinners across the state. The itinerary included cities such as San Antonio, Houston, Fort Worth, Dallas, and Austin, with the president and his delegation scheduled to deliver speeches and meet with local business leaders and party organizations. Within this framework, Dallas was identified as a key stop on the tour due to its population and economic significance.

^{Original Image of the Rifle Found in the Texas School Book Depository (}National Archives⁾

Dallas’s political climate at the time added a distinct dimension to the visit. The city was known as a center of conservative and anti-communist circles, where criticism of the federal government and particularly the Kennedy administration was intense. Certain right-wing organizations and media outlets in the city ran campaigns targeting Kennedy’s foreign policy choices, his civil rights initiatives, and his administration’s perceived “softness.” Brochures distributed before and during the visit, critical advertisements in newspapers, and rally calls signaled the atmosphere Kennedy would encounter in Dallas.

Nevertheless, the visit was planned as part of a political program aimed at reinforcing the image of “party unity” and “national cohesion” before the public. After morning speeches in Fort Worth, the delegation was scheduled to travel to Dallas, where the president would address a broad audience at a luncheon, before proceeding to Austin. The motorcade route through downtown Dallas was designed both to allow crowds to see the president and to fit within the schedule. The assassination occurred precisely during this most visible element of the Dallas program—the open-top motorcade.

On the morning of November 22, 1963, President Kennedy and his delegation attended a breakfast meeting in Fort Worth with business representatives and local officials, during which the president delivered a brief speech. After completing the morning program, the convoy proceeded to Carswell Air Force Base; President Kennedy and his wife Jacqueline boarded Air Force One for the flight to Dallas. The flight was relatively short, and Air Force One landed at Dallas’s Love Field at approximately noon local time. At the airport, the Kennedys were greeted by local officials, including Texas Governor John Connally and his wife Nellie Connally, and shook hands with a crowd gathered on the apron, engaging in brief interactions with many people.

Following the airport welcome ceremony, the president and his party transitioned to the official motorcade bound for downtown Dallas. The motorcade consisted of an open-top Lincoln Continental limousine followed by security vehicles. In the front seats sat the driver and a Secret Service agent; in the rear seats, President Kennedy sat on the right, his wife on the left, and Governor Connally and his wife sat in the middle row.

^{A Frame from the Motorcade During the Assassination (}National Archives⁾

The motorcade was planned to reach downtown Dallas and arrive at the Dallas Trade Mart building for a luncheon, where the president was scheduled to deliver a speech to business leaders and prominent citizens. Accordingly, a route was established from Love Field to downtown, selecting locations along the way to maximize public visibility.

The designated route followed major city streets from the airport to downtown Dallas, then turned onto Elm Street, crossed bridges, and headed toward the Trade Mart area. The route was considered suitable both logistically for ease of movement and for passing through dense commercial and business districts to reach large crowds. Thus, the motorcade was expected to proceed slowly through downtown, passing between crowds lining both sides of the street and under the shadows of buildings as it approached noon.

After leaving Love Field, the motorcade traveled through Dallas’s residential areas and main avenues, reaching downtown where the president’s vehicle was met with enthusiastic crowds. Proceeding along Main Street, the motorcade entered the central district, then turned onto Houston Street, and from there left onto Elm Street. This turn occurred in the Dealey Plaza area, surrounded by three-story administrative buildings and the Texas School Book Depository, which would become a symbolic landmark of the city. At this point, the presidential vehicle was moving at a relatively low speed due to the slope of the road and its approach to the overpass.

The shooting occurred at approximately 12:30 p.m. local time. As the motorcade moved along Elm Street, a series of gunshots were heard; initially, there was a moment of hesitation among the crowd and security personnel. According to eyewitness accounts, two or three shots were perceived in quick succession; one struck the president in the back and another in the head, severely wounding him. At the same moment, Governor Connally, seated in the front seat ahead of the president, was also wounded in the chest and wrist, and the interior of the limousine quickly descended into panic. The moments when Jacqueline Kennedy leaned over the wounded president and Connally was thrown backward were captured in numerous film and photographic recordings that would be examined repeatedly in the future.

Regarding the source of the gunfire, witnesses offered differing assessments during and after the event. Some witnesses attributed the sounds to the upper floors of the Texas School Book Depository building, while others believed the shots came from the grassy area within Dealey Plaza or from the vicinity of the railway viaduct. In contrast, the Secret Service agents responsible for protecting the presidential vehicle immediately decided to accelerate the limousine away from the scene; the vehicle, with sirens blaring, sped toward Parkland Memorial Hospital. Other vehicles following the motorcade also changed their routes to reach the hospital as quickly as possible.

Shortly after leaving Dealey Plaza, the presidential vehicle arrived at Parkland Memorial Hospital, where the severely wounded Kennedy and Governor Connally were immediately admitted to the emergency room. The president was carried on a stretcher to the trauma room, where intensive medical intervention was initiated by hospital staff and the presidential physician who arrived shortly thereafter. Standard emergency procedures such as chest compressions, respiratory support, and intravenous treatments were performed; however, due to the severity of the head trauma, a surgical evaluation was also conducted, and it quickly became clear that the injuries were so grave that medical efforts were unlikely to succeed.

^{News Report of Kennedy’s Condition at the Hospital (}National Archives⁾

The medical interventions at Parkland lasted approximately half an hour; at approximately 1:00 p.m. local time, President Kennedy was officially pronounced dead by the attending physicians. This determination was documented in official records and promptly communicated to the White House and relevant federal authorities. A rapid consultation took place among hospital administration, local officials, and presidential staff regarding the manner of announcing the death to the public; shortly thereafter, the media was informed that Kennedy had died at the hospital. This announcement reached wide audiences both among the crowds gathering around the hospital and through radio and television broadcasts in Dallas and other cities across the country.

Governor Connally underwent surgery at the same hospital and survived despite life-threatening injuries. Parkland Memorial Hospital thus became the center of both intense medical activity and rapidly developing political and bureaucratic decision-making processes. Preparations for the president’s autopsy and burial, disputes over jurisdiction between federal and local authorities, and heightened security measures were all carried out simultaneously. At the same time, the news of the assassination reaching Washington brought the immediate issue of filling the presidential vacuum and the status of Vice President Lyndon B. Johnson onto the urgent agenda.

Immediately after the assassination, the Dallas Police Department and other security units cordoned off the area around the crime scene and launched a comprehensive search of Dealey Plaza and the Texas School Book Depository building. Shortly thereafter, an area resembling a sniper’s position was identified on the sixth floor of the building; a clear line of sight from the window to Elm Street was confirmed. In the same area, empty shell casings and a rifle were found; the rifle later became the central ballistic evidence in the investigation. Police began identifying the names and locations of employees of the building during the incident and soon obtained a list that included Lee Harvey Oswald’s name.

Shortly after the assassination, Dallas police received a report of a police officer being murdered in the city. Patrol officer J. D. Tippit was shot and killed in the Oak Cliff neighborhood of Dallas shortly after the assassination. Eyewitness accounts described a man walking away from the scene, who was later identified as Lee Harvey Oswald. Acting on these tips, police headed to the Texas Theatre movie theater in Oak Cliff; they suspected a person inside and attempted to conduct a身份 check. A brief struggle ensued, during which Oswald, reportedly resisting arrest and attempting to reach for a weapon, was subdued and taken into custody. Thus, Lee Harvey Oswald was arrested on suspicion of both the presidential assassination and the murder of Officer Tippit.

^{Moments of Oswald’s Arrest (}National Archives⁾

Oswald was taken to the Dallas Police Headquarters, where he was interrogated regarding the assassination and the police murder. During questioning, he denied all accusations, claimed to be a “patsy,” and asserted he had no connection to the assassination. Nevertheless, police officials, based on ballistic evidence from the crime scene, employment records from the building, and eyewitness testimony, publicly identified Oswald as the primary suspect. Press representatives asked questions during brief press briefings held at the police station, and Oswald’s appearance before the public was captured by television cameras and still cameras.

In the later hours of the day, Dallas authorities officially announced that President Kennedy had been killed in an assassination, that Lee Harvey Oswald had been taken into custody as the suspect, and that investigations were ongoing at both local and federal levels. In Washington, it was announced that Vice President Lyndon B. Johnson would assume the presidency; shortly thereafter, at Love Field aboard Air Force One, Johnson took the oath of office, marking the beginning of a new era in both criminal investigation and constitutional succession within just a few hours of the assassination.

Lee Harvey Oswald was born on October 18, 1939, in New Orleans, Louisiana. His father died shortly before Oswald was born; therefore, his mother, Marguerite, became the defining figure in his childhood. The mother’s authoritarian, sometimes harsh, and unstable demeanor strained family relationships; economic hardship and the absence of a steady income led to frequent moves and relocations. This situation caused continuous disruptions in Oswald’s education and social environment.

Records from Oswald’s childhood and early youth show that he attended multiple schools briefly and was unable to complete a stable educational process due to frequent transfers. These records indicate that he performed poorly academically, experienced disciplinary problems, and exhibited a largely isolated profile. Teachers and school staff described Oswald as introverted, easily angered, and prone to conflict with authority; he was sometimes reported to have engaged in violent behavior.

^{Harvey Oswald Being Taken to Jail (}National Archives⁾

During adolescence, absenteeism and conflict with authority became more pronounced; Oswald was therefore subjected to psychiatric evaluation. The assessments did not diagnose a clear mental illness but indicated emotional instability, difficulty with social adaptation, and serious problems in family relationships. Nevertheless, Oswald was returned to his mother; the tense family environment and frequent relocations reinforced his social isolation.

As he approached age 17, Oswald joined the United States Marine Corps, viewing military service as both an economic opportunity and a framework to bring order to his life. However, contrary to these expectations, Oswald struggled to adapt to discipline, failed to conform to the chain of command, and frequently clashed with superiors. His peers often described him as introverted, a target of ridicule and exclusion, and gave him nicknames.

During his military service, Oswald received basic training in firearms and marksmanship; his shooting training later became a frequently cited element in assassination debates. However, his disciplinary infractions and an incident involving a firearm accident led to negative entries in his military record. While stationed at the Atsugi base in Japan, the local political and social environment influenced his worldview. Oswald developed an interest in socialist and Marxist literature, extensively read about communism and the Soviet Union, and increasingly sought to identify with these ideas.

Before completing his military service, Oswald developed the idea of defecting to the Soviet Union and soon acted on it. In late 1959, he left the United States via Europe and arrived in the Soviet Union, where he applied to Soviet authorities for citizenship. During this process, he presented himself as someone who had broken with America due to his Marxist beliefs and emphasized his desire to settle scores with the American system. Although his request was initially met with ambiguity, Soviet authorities eventually permitted Oswald to remain in the country and assigned him to Minsk.

In Minsk, Oswald received modest financial assistance through the Soviet Red Cross; he was reportedly paid around 5,000 rubles, which provided economic security during the initial period. He was assigned an apartment without rent and employed at the Byelorussian Radio and Television Factory. His official salary, by Soviet standards, was relatively favorable; Oswald lived at a standard comparable to other workers in his department. However, he was continuously monitored by Soviet security services, and some individuals in his circle were found to be fulfilling surveillance functions on behalf of the state.

Oswald soon realized a significant gap between his initial expectations of the Soviet system and the reality he encountered; he gradually became increasingly dissatisfied with life in Minsk. The monotony of his work environment, the rigidity of political and social life, bureaucratic restrictions, and unmet expectations regarding freedom distanced his Soviet experience from the “ideal” he had envisioned. During this period, Oswald formed friendships while also expressing his criticisms of the Soviet system to close associates. His relationship with Marina Prusakova, whom he met and married during this time, became one of the central elements of both his Soviet years and his subsequent American life.

After several years in Minsk, Oswald began to question his decision to remain in the Soviet Union and formally requested permission to return to the United States. Although the Soviet side initially responded coldly to this request, they eventually granted the necessary permissions; Oswald returned to the United States in 1962 with his wife Marina and their newborn child.

Oswald’s childhood and youth experiences of isolation and conflict with authority evolved into efforts to express himself politically. His early interest in leftist thought and Marxist literature sharply distinguished him from mainstream American political culture during the Cold War. His attempt to defect to the Soviet Union and his several years living there emerged as radical expressions of this ideological orientation; this step, extremely unusual in American public opinion at the time, solidified Oswald’s political identity.

After returning to the United States, Oswald did not abandon his ideological stance; instead, he sought to make his worldview more systematic and visible. His experience in the Soviet Union led him to adopt a perspective that criticized both sides rather than choosing between them. Nevertheless, he continued to promote anti-imperialist, anti-capitalist, and anti-Western rhetoric, particularly expressing sympathy for the Cuban Revolution and Fidel Castro’s regime through various activities.

In the summer of 1963, while in New Orleans, Oswald operated under the name of the “Fair Play for Cuba Committee”; he distributed pamphlets and organized street demonstrations. He addressed the public through “Hands Off Cuba” slogans and handbills; these activities led to debates, altercations, and police interventions that were covered by local media. Later investigations revealed that Oswald’s organizational activity in New Orleans was largely self-initiated and conducted within a very limited circle; his connection to the national structure of the organization was weak. Nevertheless, this period was significant as it marked Oswald’s first public appearance as a political figure.

Another manifestation of Oswald’s political motivations was his personalization of anger toward individuals and groups he viewed as “domestic enemies.” His attempted armed attack on former General Edwin Walker is significant in this context. Oswald viewed Walker as an extreme right-wing, anti-communist, and repressive figure and planned an action against him; late at night, he fired shots at Walker’s home in Dallas, but the bullets missed their target. This act, when linked to evidence uncovered after the assassination, was interpreted as an example of Oswald’s ability to plan and execute individual acts of violence motivated by political beliefs.

In this context, Oswald positioned himself in direct opposition to the widespread anti-leftist atmosphere in the United States; he presented himself as a figure identifying as leftist, anti-imperialist, and anti-system. Both his Soviet experience and his activism in New Orleans and Dallas were decisive in shaping this political identity.

After returning from the Soviet Union, Oswald, along with his wife Marina and children, lived briefly in various cities before moving to the Texas region. In Dallas and its surroundings, Oswald was forced to accept low-quality and relatively temporary jobs; economic hardship and family tensions became defining features of this period. His lack of continuity in employment stemmed from both his personal character and limited professional skills.

In 1963, Oswald obtained a job at the Texas School Book Depository in downtown Dallas. This building, owned by a company supplying textbooks and educational materials to Texas schools, was a multi-story structure consisting of storage floors and administrative offices. Oswald worked in a physically demanding role, handling and organizing book crates. Colleagues described him as an employee who was largely introverted, quiet, and maintained limited social interactions.

Due to its proximity to downtown Dallas and its height, the building became a prominent point along the motorcade route from Love Field to downtown. After the president’s Dallas visit itinerary was finalized, it became clear that the motorcade would pass through Dealey Plaza and that the street where the Texas School Book Depository was located would be on the route. This situation placed Oswald in a critical position within the assassination scenario, given both his access to the building and the clear line of sight from its upper floors to the street.

Investigations after the assassination revealed that Oswald arrived at the building on the morning of the incident, carried a package, and described its contents as “curtain rods.” Various eyewitnesses indicated that a specific area on the sixth floor, arranged with cardboard boxes to provide a clear view outward, resembled a “sniper’s nest.” The rifle and empty shell casings recovered from the same area were linked to a weapon identified as belonging to Oswald; thus, his location within the building became one of the key elements placing him at the center of the investigation.

On the day of the assassination, following President Kennedy’s admission to Parkland Memorial Hospital and his subsequent death, the Dallas Police Department and other security units launched a broad investigation. During the search of the Texas School Book Depository, the rifle and shell casings found on the sixth floor immediately focused attention on the building’s employees; a quick headcount soon revealed that Lee Harvey Oswald was missing. This information placed him in the category of a potential suspect.

At the same time, a report was received that police officer J. D. Tippit had been shot and killed in the Oak Cliff neighborhood of Dallas. Eyewitnesses described a man fleeing the scene, whose description was later linked to Oswald. Acting on these tips, police headed to the Texas Theatre movie theater in Oak Cliff and identified a person exhibiting suspicious behavior. During an attempt to conduct a identity check, a brief struggle ensued; Oswald, who reportedly resisted the police officers, was subdued and taken into custody. Thus, Oswald was taken to the Dallas Police Headquarters on suspicion of both the presidential assassination and the murder of Tippit.

At police headquarters, Oswald underwent multiple interrogations at different times. The interrogations involved not only police officers but also FBI and Secret Service agents; however, none of these interrogations were fully recorded on audio, and only fragmented notes taken by various officers served as documentation. Oswald denied all accusations, claiming he had no connection to Kennedy’s murder, did not shoot Tippit, and was being framed as a “patsy.” Disputes arose over whether his requests for legal counsel and his right to legal representation were adequately addressed in the chaotic environment; these issues became major points of contention in later years.

In the early hours of the investigation, Oswald was formally charged primarily with the murder of police officer Tippit. As evidence was evaluated, the rifle found in the Texas School Book Depository was linked to a weapon Oswald had purchased, photographs showing Oswald holding the rifle, eyewitness testimony regarding his location in the building, and his brief escape route all contributed to the formal charge of involvement in the presidential assassination. Thus, Oswald was formally charged with both the presidential assassination and the murder of Tippit within a short time.

While Oswald was held at police headquarters, a media environment developed around him; the progress of the investigation became a process closely followed by the public. Brief press briefings held at police headquarters, along with photographs and footage taken during transfers between corridors and rooms, increased Oswald’s visibility before the public. However, this period ended abruptly on November 24, 1963, when Oswald was shot and killed by Jack Ruby in the basement of the Dallas Police Headquarters. Oswald’s death before any court proceedings could be completed prevented the systematic presentation of evidence related to the assassination in court and created enduring questions about his motivations and possible connections.

Jack Ruby, born Jacob Leon Rubenstein, was born in 1911 in the United States into a low-income and troubled family environment. His childhood and early youth were shaped by economic hardship, frequent relocations, and family conflicts; this led to an unstable education and immersion in street culture. From a young age, Ruby worked in various small jobs and was known for his aggressive temperament, quick temper, and occasional resort to violence.

^{At the Moment Oswald Was Shot, the Person Screaming in Pain Is Seen on the Far Right (}National Archives⁾

In adulthood, Ruby turned to business, establishing a career especially linked to the entertainment industry after the war. After settling in Dallas, he began operating bars and nightclubs; his establishments in the city center became known for striptease and live music programs. Relationships he built with employees and customers played a significant role in his interactions within both the business world and the local police force. His close relationship with certain officers in the Dallas police force, offering discounts or free drinks at his clubs, and establishing himself as a “recognized figure” within this circle became one of the factors explaining how he gained access to the police headquarters during Oswald’s killing.

^{The Gun Used by Jack Ruby to Kill Oswald (}National Archives⁾

Witness accounts of Ruby’s character describe him as extroverted, attention-seeking, and emotionally volatile. He enjoyed presenting himself as “colorful” and “different”; alongside his aggressive outbursts, he was noted to have a highly emotional nature. There are testimonies indicating that he occasionally resorted to physical violence in business disputes, carried a firearm, and struggled to control his anger. Nevertheless, some close associates described him as “overly emotional,” nationalist, and disturbed by anti-Kennedy rhetoric. This complex personality profile has frequently served as a contextual framework for interpreting Ruby’s actions on November 24, 1963.

Two days after the assassination, on Sunday, November 24, 1963, the Dallas Police Department planned to transfer Lee Harvey Oswald from the city jail to the county jail. The transfer was scheduled for the afternoon, to be conducted from the basement of the police headquarters, with Oswald being transported by police vehicles to another facility. The event was under unprecedented media attention, given the communication conditions of the era; local and national television crews, photographers, and reporters had taken their positions behind barriers in the basement to observe and film Oswald’s transfer live.

At the same time, Jack Ruby continued his routine daily activities. He was observed tracking routine operations at his clubs early in the morning and making brief contacts around downtown during the day. It was determined that he visited a telegram office that day to send money to an acquaintance and, shortly after leaving the office, headed toward the area of the Dallas Police Headquarters. Ruby entered the building with his small dog and a pistol; he was able to blend into the crowd of reporters and police officers without being noticed. The ease with which Ruby, as a civilian, entered the building and reached the critical basement area raised serious questions about the adequacy of security protocols from the outset.

^{The T-Shirt Oswald Was Wearing When He Was Killed (}National Archives⁾

As Oswald, handcuffed and escorted by two police officers, descended from the interrogation room to the basement, television cameras were recording. While being led toward the police vehicle prepared for the transfer, Jack Ruby suddenly stepped forward from the crowd, pointed a short-barreled pistol at Oswald’s chest, and fired; the bullet struck Oswald’s body. The moment was instantly broadcast live on television; as Oswald collapsed to the ground, nearby police officers subdued Ruby. Oswald was immediately transported to Parkland Memorial Hospital but died shortly thereafter. Thus, the primary suspect in the assassination was killed while under police protection, before appearing in court; this development fundamentally altered the course of the investigation and public perception.

Ruby was taken into custody immediately after being apprehended at the scene and began to be interrogated in the same building. In the initial phase, he stated he was aware of what he had done; later, he attempted to explain his act using both emotional and “national” justifications. He emphasized his admiration for Kennedy and his reaction to what he perceived as disrespectful statements toward the president, particularly citing the influence of extreme right-wing propaganda and offensive advertisements in Dallas. He also argued that the prolonged public debate surrounding Oswald’s court proceedings would be a great source of anguish for the Kennedy family, especially Jacqueline Kennedy; therefore, he claimed his act was an emotional response aimed at “protecting the country and the president’s family from shame.”

Ruby’s justifications during interrogation and trial were intensely debated from psychological and legal perspectives. The defense argued that his mental state should be considered, drawing on his history of emotional instability, violent tendencies, and family problems to construct a profile of “instability.” In contrast, the prosecution viewed Ruby’s act as a deliberate killing, even if not premeditated; they emphasized his entry into the police headquarters armed, his knowledge of Oswald’s transfer schedule and route, and his ability to infiltrate the basement crowd and fire within seconds as indicators of intent.

^{Chaos After Oswald’s Death, Oswald’s Body Visible on the Left (}National Archives⁾

In the Dallas trial, the jury found Ruby guilty of “intentional murder” and sentenced him to death. This verdict, while not exceptional under Texas law at the time, was highly notable given the national and international dimensions of the case. Ruby’s lawyers appealed the verdict, alleging various procedural errors related to jury selection, public pressure, media influence, and the evaluation of evidence. Appellate courts, considering certain procedural irregularities and factors that may have compromised the court’s impartiality, overturned the original verdict and ordered a new trial.

However, Ruby faced serious health problems before the new trial could take place. While in prison, he contracted a disease that rapidly progressed, physically weakening him; medical examinations indicated a fatal form of cancer. In early 1967, Ruby was hospitalized and died under prison supervision before the second trial could be completed. Thus, like Oswald, Ruby died without ever having the opportunity to fully explain his actions and possible connections in court; this meant that the judicial dimensions of the assassination were never fully resolved.

Jack Ruby’s killing of Lee Harvey Oswald under police supervision fundamentally altered the course of debates surrounding the Kennedy assassination. From the outset, the event raised the question: was it a spontaneous outburst of anger or a planned operation to silence Oswald? Oswald’s survival and subsequent formal questioning in court, which would have allowed evidence to be systematically debated before the judiciary and the public to form opinions based on recorded testimonies, was eliminated by Ruby’s act. This left many questions regarding the assassin and possible accomplices unanswered.

^{After Oswald’s Death, the Texas Police Headquarters and the Arriving Ambulance (}National Archives⁾

Claims that Ruby, as a nightclub owner, had contacts with organized crime circles and was closely associated with individuals linked to gambling and illegal activities became central to conspiracy theories following the assassination. Some commentators suggested that tensions between the Mafia and federal authorities, particularly regarding Kennedy administration policies against organized crime, could have made Ruby part of a broader conspiracy. Similarly, assessments implying Ruby’s connections to Cuba and anti-Castro activities placed him within intelligence operations and foreign policy-oriented conspiracy scenarios. Soviet and other foreign intelligence analyses also viewed Ruby’s role as an “extraordinary security vulnerability,” emphasizing that such an easy silencing of a suspect raised institutional-level questions.

^{The Jacket Oswald Was Wearing When He Was Killed (}National Archives⁾

On the other hand, interpretations emphasizing Ruby’s psychological and personality traits viewed his act not as part of an organized conspiracy but as the product of an emotional and impulsive response. According to this perspective, Ruby was deeply devastated and enraged by the president’s murder, felt guilt due to the propaganda and insults against Kennedy in Dallas, and killed Oswald to achieve his own sense of “justice” and to absolve himself from this environment. This approach defines the act as an individual outburst of violence, taking into account Ruby’s personality, emotional reactions, and past behavioral patterns.

Official investigations did not announce any concrete findings proving Ruby acted within a conspiracy; however, they also failed to fully dismiss the significance of the security failures and the questions raised by Ruby’s connections with the police force. This dual situation transformed the Ruby incident into one of the most controversial elements of the Kennedy assassination. Ultimately, Jack Ruby’s killing of Oswald narrowed the evidentiary and testimonial basis of the investigation while simultaneously establishing itself as one of the strongest sources of nourishment for the conspiracy culture surrounding the assassination.

The first official response to the Kennedy assassination was the investigation launched by the Dallas Police Department at the crime scene and surrounding areas. Dealey Plaza was quickly cordoned off, and buildings along the route, especially the Texas School Book Depository, were placed under control. Police initially attempted to determine the direction of the gunfire based on eyewitness accounts; parallel to this, they conducted a systematic search of the Depository building. The discovery of an area on the sixth floor, surrounded by cardboard boxes and offering a clear line of sight from the window to Elm Street, significantly altered the course of the investigation. Three empty shell casings and a rifle were found in the same area, prompting police to focus on the building’s employees.

Dallas police quickly conducted a headcount of the building’s personnel to determine their whereabouts during the incident; this revealed that Lee Harvey Oswald had left the building. This information quickly placed Oswald in the category of a “person of interest.” Simultaneously, the murder of police officer J. D. Tippit shortly after the assassination increased the complexity of the investigation. Based on eyewitness accounts, Dallas Police, while searching for the perpetrator of the Tippit murder, headed to the Texas Theatre movie theater following tips; they arrested a person believed to be hiding there. It was determined that the arrested individual was Lee Harvey Oswald, and police announced on the same day that they had apprehended the suspect in both the assassination and the Tippit murder.

After Oswald was brought to police headquarters, the interrogation process became one of the most controversial aspects of the investigation. No audio recordings were made during the interrogations; the sessions were not documented in full written transcripts, and only scattered notes taken by responsible officers remained as permanent records. Oswald’s statements regarding his request for legal counsel and his legal status remained within an ambiguous framework due to intense media pressure and lack of institutional coordination; this situation created a basis for criticism of the investigation’s procedural aspects. On the other hand, Dallas Police rapidly compiled ballistic data, eyewitness statements, and physical evidence from the Depository building to formally charge Oswald with both the assassination of the president and the murder of Tippit.

Dallas police investigative practices were heavily criticized on two main grounds. First, deficiencies in preserving the chain of evidence and securing the crime scene. Allowing numerous officers and journalists to move freely around the crime scene and the Depository building resulted in unclear standards for collecting and handling evidence, which were later recorded as serious procedural issues.

Second, the inadequacy of security measures during Oswald’s detention and transfer enabled Jack Ruby to enter the basement and shoot Oswald. The killing of a suspect under police protection, in front of live television cameras, left a lasting shadow on the institutional capacity and procedures of the Dallas Police Department; these security failures were thoroughly examined in subsequent official investigations.

The FBI and Secret Service were also involved in the investigation during this early stage, but coordination between local police and federal agencies was never fully established. The operations conducted in Dallas during the first days established the foundational framework for evidence collection and witness interviews; this material became the primary data source for subsequent federal investigations.

Immediately after President Kennedy’s death, Lyndon B. Johnson, who assumed the presidency, believed that the investigation conducted solely by local authorities was insufficient and that a nationally trusted investigative mechanism needed to be established. Accordingly, on November 29, 1963, a presidential proclamation established the President’s Commission on the Assassination of President Kennedy, known publicly as the Warren Commission.

The commission’s chairmanship was given to Earl Warren, Chief Justice of the United States Supreme Court at the time; members included Senator Richard Russell, Senator John Sherman Cooper, members of the House of Representatives Hale Boggs and Gerald Ford, former CIA Director Allen Dulles, and former World Bank President John J. McCloy. Thus, a seven-member body was formed, representing the legislative, executive, and judicial branches as well as intelligence and foreign policy circles.

The commission’s mandate was to investigate all aspects of the assassination, identify the perpetrator or perpetrators, examine the possibility of a conspiracy or foreign involvement, and report its findings to the public. During its work, the commission operated with a large team of lawyers and researchers, reviewed evidence collected by Dallas Police, the FBI, the Secret Service, and other federal agencies, and interviewed hundreds of witnesses through written statements or oral testimony. The commission’s investigation ultimately produced an eleven-volume main report and a total of twenty-six volumes including witness testimonies, documents, and technical analyses.

The Warren Commission’s final report, published in 1964, concluded that Lee Harvey Oswald acted alone in assassinating Kennedy. According to the report, the rifle and shell casings found on the sixth floor of the Texas School Book Depository were ballistically linked to a weapon Oswald had purchased. Based on the Zapruder film and other visual evidence, three shots were fired; the first missed the target, the second entered Kennedy’s back, exited through his throat, and also wounded Governor Connally, and the third struck Kennedy in the head, causing fatal injuries. This scenario formed the basis of what became known in public opinion as the “single-bullet theory.” The commission also evaluated Oswald’s political and personal history and concluded that no conclusive evidence existed linking him to any organized conspiracy involving the Soviet Union, Cuba, or other foreign powers.

Regarding Jack Ruby’s killing of Oswald, the commission reached a similar conclusion: there was insufficient evidence to prove that Ruby acted on behalf of the Mafia or any other organized structure; the act appeared to be more of an emotional and individual response. However, the commission identified serious deficiencies and communication problems in the security arrangements of both the Dallas Police Department and the Secret Service; it acknowledged that information sharing and coordination among federal agencies had been inadequate.

The Warren Commission faced intense criticism in subsequent years regarding both its methods and its conclusions. A major part of the criticism focused on the commission’s excessive reliance on preliminary reports and files prepared by the FBI and other federal agencies, and its limited independent investigation. Additionally, it was argued that contradictions in some eyewitness testimonies were not adequately examined and that autopsy and medical findings were not thoroughly and transparently evaluated through technical reports and photographic and film materials.

The ballistic and anatomical defensibility of the “single-bullet theory” remained a subject of prolonged debate among experts and the public; the extent to which the commission’s conclusion of “no conspiracy” aligned with the integrity of the evidence was questioned. Nevertheless, the Warren Commission Report remained the primary reference text in official historiography for many years.

After the Warren Commission completed its work, debates surrounding the Kennedy assassination continued throughout the late 1960s and early 1970s, with various expert groups, independent researchers, and journalists publishing works criticizing the commission’s report. During this period, some official and semi-official initiatives emerged to re-evaluate medical and ballistic evidence. Limited access to autopsy materials, restrictions on the use of photographic and film recordings, and the secrecy regime governing archival documents emerged as factors that hindered both scientific analysis and public oversight.

In the mid-1970s, the Watergate scandal and the exposure of intelligence agencies’ domestic activities significantly weakened public trust in federal institutions; congressional committees were established to examine the practices of the CIA, FBI, and other security agencies. In this climate, suspicions regarding the Kennedy assassination were renewed, and political will emerged to review the findings of the Warren Commission. Accordingly, in 1976, the House Select Committee on Assassinations (HSCA) was established within the House of Representatives; the committee was tasked with re-examining both the Kennedy assassination and the assassination of Martin Luther King Jr.

The HSCA gained access to previously undisclosed or limited-use documents, re-interviewed witnesses, re-evaluated autopsy and ballistic materials, and commissioned expert analyses, particularly on acoustic evidence. An acoustic analysis conducted on a recording allegedly from the Dallas Police Radio indicated that four shots were fired and that one of them may have originated from the grassy area, suggesting the possible presence of a second shooter.

The HSCA’s final report, published in 1979, maintained the conclusion that Lee Harvey Oswald fired from the sixth floor of the Texas School Book Depository and killed the president; however, based on acoustic analysis and some eyewitness testimonies, it concluded that “the president was probably assassinated as a result of a conspiracy.” However, the committee was unable to definitively identify the individuals or organizations involved in the conspiracy and merely noted the presence of “undetermined factors.”

The HSCA Report also strongly criticized the performance of federal agencies before and after the assassination. It stated that the FBI and CIA failed to share information they possessed regarding Oswald, that the Secret Service inadequately assessed the risks to the president’s protection, and that numerous aspects—from the route selection to protective protocols in Dallas—lacked necessary sensitivity. These criticisms laid the groundwork for discussing the assassination not only
