“The most investigated crime in world history — the assassination of President John F. Kennedy on Nov. 22, 1963 — gets yet a new theory when ReelzChannel premieres the original investigative doc JFK: The Smoking Gun on Nov. 3,” deadline.com reports. “[The documentary] comes to a genuinely fascinating conclusion: There was a second shooter during that fateful day in Dallas, and it wasn’t an assassin. It was a Secret Service agent named George Hickey, who was riding in the car in the motorcade directly behind Kennedy’s vehicle and whose automatic weapon accidentally discharged.” Author Bonar Menninger and a retired Australian detective Colin McLaren reckon “the truth” was covered up at the highest levels of United States intelligence and by JFK’s brother Robert. “The lone gunman theory is nonsense and always has been.” Yeah, this is way more credible. But not the first time someone’s blamed a Secret Service agent for the head shot.
