Giancana definitely sticks out in that category. Shot in the back of the head while in his own home by someone he was comfortable enough with to invite inside and cook sausage+peppers for. It had to be someone close to him. No doubt about it.
Is it Giancana where it's said that the Feds/ police were always watching him and in that small amount of time when they were "called away" his assassin arrived and killed him. Biasi??butch?
That whole Genovese/Philly plot was betrayals all over; Bruno by Bananas: Bananas by Tieri
