JFK: Did Oswald act alone in assassinating Kennedy?

In 1964, the Warren Commission concluded that Lee Harvey Oswald acted alone in assassinating Kennedy, firing three shots. One shot apparently missed the limousine entirely, another struck Kennedy and Texas Governor John Connally, and another struck Kennedy in the head. This conclusion was supported by prior investigations carried out by the Federal Bureau of Investigation (FBI) and Dallas Police Department.

The circumstances surrounding the assassination of John F. Kennedy on November 22, 1963, spawned suspicions of a conspiracy. Critics have argued that the Commission and the government have covered up crucial information pointing to a conspiracy.

November 22, 2013 marks the 50th anniversary of President John F. Kennedy's assassination in Dallas, Texas.
