For me,the most difficult part of accepting the Hickey-as-killer of JFK is that in all of the photos and movies of the assassination,Hickey is never seen holding a rifle prior to the fatal head shot. It is only after that shot that Hickey is seen with his weapon. Even the iconic Dealy Plaza photos taken by Ike Altgens,do not show Hickey with a rifle in his hands until after the fatal shot. All of the ballistic "evidence" and Secret Service coverup conspiracy is moot,since Hickey couldn't have killed JFK with a rifle he wasn't holding.
