More than 120 alleged mobsters were arrested Thursday, in what the FBI calls the biggest mafia bust in history. The stack of charges includes murder, racketeering, illegal gambling and narcotics trafficking, reaching back decades in some cases. Henry Hill is a former associate of the Lucchese family, one of the seven familes hit in Thursday's takedown. Hill turned informant for the FBI in the early 1980's, and his story was the basis for the acclaimed 1990 film Goodfellas. In an interview with Don Lemon, Hill explains why he thinks organized crime will never die, and tells us whether he still looks over his shoulder.
