The controversy about the assination has always centered on the 3rd (kill shot) fired at JFK. A new documentary produced by REELZ channel called JFK the smoking gun does an excellent job of sorting out all the facts. The show not only explains where the shot came from, plus who fired it, but also why the cover up. What the show does not explain is who put Oswald up to his part of the assination. Was it Castro, was it the Mafia, or was he alone?
