I think that kennedy was killed by the mafia and cia. Jfk father promised to the mob that his son will close both eyes on the mob but jfk made the opposite; jfk was against the war in Vietnam and the bay of pigs invasion failed due he denied the aviation cover. So that behind a mr nobody that was a worst shooter that killed the president and after was killed by a mob associate that after few years died in prison due a providential cancer; I think there was the mob and the cia.
