I was just listening to him. Maha Rushie told it as it really was. On a personal note, I believed the mafia had JFK killed until I heard Gerald Posner on tv. Communist Oswald had a nasty temper with Marina (his wife) and Marina used to tease Oswald how handsome Pres. Kennedy was and how Pres. Kennedy reminded Marina of a very handsome boyfriend of hers in Minsk.
I do, however, believe the theory that Secret Service George Hickey in the car following Kennedy accidentally delivered the head shot in the chaos of the moment:
Accidental assassin: JFK theory alleges Secret Service agent fumbled gun
I was convinced by the documentary JFK: The Smoking Gun
You can find it online and watch it for free.
If you watch the Zapruder film, the shot that blew Kennedy's head apart obviously is different that the shot the hit him in the throat.
Oswald was using full metal jacket bullets, which do not expand. The second shot is not a full metal jacket bullet.
You are aware that the House Select Committee on Assassinations concluded that four shots were fired and that there was a conspiracy?
