There is no doubt in my mind that Carlos Marcello was behind this. The people who believe the Warren commission are nuts
100%
so very true, he also admitted it.
His lawyer has confirmed this repeatedly as well.
Jack Ruby has FBI documents linking him to Nappi and the rest of the Chicago Outfit going back to the 40s and is linked with Red Dorfman whose son Alan was the bagman for the Teamsters insurance fund.
Every single person involved or suspected has a direct link to organized crime, specifically Chicago/NO/FL mafia.
