Whether you believe it was E. Howard Hunt on the grassy knoll, the CIA, the Mafia, the Teamsters, the military, "right wing extremists", Richard Nixon or little green men from area 51, all Kennedy conspiracy theories exist for the same purpose - to exonerating the Oswald and to deflect from the fact that a communist assassinated the President.
You can check out pictures of Kennedy lying dead on a table. His face and forehead are intact. It’s the back of his head that is in shambles.
