The assassination of President John F. Kennedy on November 22, 1963 has spawned numerous conspiracy theories.^[1] These theories allege the involvement of the CIA, the Mafia, Vice President Lyndon B. Johnson, Cuban Prime Minister Fidel Castro, the KGB, or some combination of these individuals and entities. Some conspiracy theories have alleged a coverup by parts of the federal government, such as the original FBI investigators, the Warren Commission, or the CIA. Former Los Angeles District Attorney Vincent Bugliosi estimated that a total of 42 groups, 82 assassins, and 214 people had been accused at one time or another in various conspiracy scenarios.^[2]
