The book presents the final report of the President Commission created to investigate the assassination of John Fitzgerald Kennedy on November twenty-second, nineteen-third, in Dallas, Texas. The text details the narrative of the presidential motorcade, the shots fired from the sixth floor of the Texas School Book Depository, the subsequent murder of Patrolman J.D. Tippit, and the apprehension and subsequent killing of Lee Harvey Oswald by Jack Ruby.
The authors analyze extensive witness testimonies, medical reports from Parkland Memorial Hospital, the autopsy performed at Bethesda Naval Hospital, and firearms identification evidence. The Commission establishes that the shots were fired from the southeast corner window of the Depository Building using a Mannlicher-Carcano rifle owned by and in the possession of Lee Harvey Oswald. The evidence indicates that two bullets caused all the wounds suffered by President Kennedy and Governor John Connally.
The report reviews Oswald's background, his time in the Soviet Union, his return to the United States, his pro-communist activities, and his unsuccessful attempts to travel to Cuba. The Commission explores the possibility of domestic or foreign conspiracies and concludes that no credible evidence links Oswald or Jack Ruby to any conspiracy. All investigations established that Oswald acted alone in assassinating the president.
Finally, the report evaluates the security and protective measures employed by the United States Secret Service and other federal agencies during the Texas trip. The Commission formulates several recommendations to improve presidential protection, enhance inter-agency communication, and overhaul intelligence procedures to prevent future threats against the executive branch.
