I have a photograph taken at the time JFK was shot in the throat. The photo shows Hickey without a rifle in his hand, meaning he had no more than 2 seconds to reach for the gun, take off the safety, aim the gun, and hit a moving target with precision. In short, Hickey couldn't have shot the president accidentally or otherwise. However, the theory that shots came from Hickey's direction are reasonable if you look behind him. An open window, hidden behind a fire escape that no longer exists, on the 2nd floor of the DalTex building was directly behind and above Hickey's head. One of the several spots the assassination team probably used.
