It doesn't matter if some other people were talking about taking JFK out. It doesn't change the fact that Oswald killed the President. There was no connection between him and the mafia. There didn't need to be either, he had his own motives. There is a mountain of motive there, more than anyone in the mafia could of given him. He was a derranged liberal through and through. He admired communists/socialists, and he hated America. Ironically he would of felt right at home with modern day libs.
