The President's Commission on the Assassination of President Kennedy, unofficially the Warren Commission, released its final report in 1964 and attributed the assassination of President John F. Kennedy (JFK) to three shots fired from a single marksman behind the presidential limousine with two bullets striking the president from the rear. While the first shot missed, the second shot caused a neck wound to Kennedy. The third and fatal shot hit Kennedy in the head [84].
Controversy concerning the commission report arose due to a physician in the overall disarray describing the neck wound from the second shot as a bullet entrance from the front throat [26], [76], [84], [88]. Considerable doubt regarding the shot direction was further raised by the testimony of over 40 eye witnesses, including treating doctors, who unanimously reported a large wound in the right back of Kennedy’s head [15], [2], [20], [50], [84], contradicting the official version of a large wound in the temple region of the right frontal bone. Further contradiction was added by the film from a civilian bystander [91], known as the Zapruder Film, showing the president’s head snapping violently backward upon impact with the third shot. Intuitive interpretation of this backward movement led to a lay verdict that the projectile must have come from the front.
