His dad was a major bootlegger, real good friends with Joseph Costello, one of the original "New York 5" crime family members.
In the 50s when CIA hits were legal and actually sanctioned, many of the hits were done by mob folks, why waste a trained CIA agent to bump off some 3rd world dictator.
There is no doubt in my mind that old man Joe used his mob connections to get his son elected, after they were used, the double cross began as JFK (with his Dads direction) let Bobbie loose on them.
I honestly think JFK knew he had some out-of-control folks running around in the CIA and that's why he fired CIA Director Alan Dulles after the Bay of Pigs. Another coincidence - Dulles' brother was the Mayor of Dallas, November 1963 and the head of the Dallas Police force (a great position to be in if you were involved in the assassination attempt). Alan Dulles later served on the Warren Commission. That Would of been like Newt Gingrich acting as counsel for Clinton during the Monica Lewinsky trial!!!!
