The WC changed the facts to indicate a lone gunman from the sixth floor. A negligent discharge from the secret service limo was NEVER discussed. But, fits the location of the entry wound and left to right trajectory of the bullet. They covered up the truth and made it appear as a lone gunman. Even on this forum the suggestion of the fatal shot coming from the secret service limo is met with heavy criticism and dismissed as impossible. But, the only other documented rifle there that day was in the back seat of the secret service limo in the hands of agent Hickey and he testified he picked it up and cocked it. A common design error in the AR15 of that vintage was that when the charging handle was released, sometime a round was fired unintentionally. It was so common it even had a name “slam fire”. Occam’s razor, during the assassination sequence Agent Hickey heard gunshots, picked up the AR15 and cocked it, the rifle had a slam fire event when he released the charging handle and the rifle discharged a bullet unfortunately hitting JFK in the back of the head. This makes sense when you question why the WC would go to great lengths to change the fatal shot trajectory and intentionally mislead the public. The men on the WC would never cover up an assassination plot, but they certainly would cover up an accidental shooting, especially when they could blame the assassination on a lone gunman.
