Executive summary

The Warren Commission concluded that Lee Harvey Oswald was lawfully taken into custody after resisting arrest in the Texas Theatre and that while he was not abused during his detention, Dallas police failed to control the chaotic press environment and provide adequate security that ultimately allowed Jack Ruby to shoot Oswald in police custody [1] [2] [3]. The Commission found no evidence that Dallas police assisted Ruby or that Ruby and Oswald were part of any wider conspiracy, but it criticized lapses in crowd and media control as key causes of the security breakdown [4] [2] [5].

1. Arrest and immediate custody: how Oswald was taken and charged

The Commission recorded that Oswald resisted arrest at the Texas Theatre, produced a pistol during the struggle, and sustained minor injuries (a cut over one eye and a bruise under the other) in the course of being subdued, after which he was placed in Dallas police custody and later formally charged with the murders of President Kennedy and Officer J. D. Tippit [1] [6] [3]. It traced routine investigative steps—fingerprinting, interrogation sessions, and arraignment—documenting that Oswald spent almost all of his final 48 hours in the Police and Courts Building under the supervision of Dallas authorities [2] [7].

2. Treatment in custody and legal rights: the Commission’s assessment

The Warren Commission explicitly rejected claims that Oswald was the victim of police brutality while in custody, stating that during the time he was detained he was neither ill-treated nor abused; the report supported this conclusion with medical and witness accounts of the minor injuries tied to the arrest struggle [1]. The Commission also noted that the Dallas police kept the press informed of Oswald’s treatment, reflecting an official stance that transparency and media presence helped guard against allegations of mistreatment even as that access itself created problems [2] [1].

3. Security planning and the abortive transfer: where safeguards failed

Although Dallas police took “special security measures” given worldwide attention, the Commission concluded those measures did not include adequate control of the enormous crowd of newsmen and onlookers that inundated headquarters, a failure the report singled out as a key factor in the eventual killing of Oswald [2]. The Commission detailed an “abortive transfer” procedure and the ordinary practice that county sheriffs assume custody after a felony arrest, but highlighted confusion and the breakdown of crowd control on the third floor and in the basement corridors where Ruby gained access [2] [8].

4. The shooting of Oswald and assignment of responsibility

On November 24, while being moved from the city jail toward the county sheriff’s office, Oswald was fatally shot by Jack Ruby in the police headquarters basement; the Commission traced the events, reviewed testimony and exhibits, and concluded Ruby acted alone in killing Oswald and that there was no evidence Dallas police assisted him [3] [4] [6]. At the same time, the Commission apportioned blame not to individual officers as conspirators but to systemic failures—insufficient crowd control and lax press management—that produced “a breakdown of law enforcement” enabling Ruby’s act [5] [2].

5. The Commission’s broader conclusions and limits of its findings

The Warren Commission’s determinations supported its larger thesis that Oswald acted alone in the assassination and that Ruby’s killing of Oswald was not part of any conspiracy, findings reiterated across summaries and appendices [9] [4] [10]. However, the report also acknowledged extraordinary circumstances and world attention that complicated Dallas police work and admitted that its criticism centered on operational lapses—particularly media control and transfer procedures—rather than evidence of collusion; sources beyond the Commission have since debated whether those operational failings were adequately explained or investigated further [2] [5] [10].
