I think the FBI would rather see him rot in jail rather than assassinate him.
For sure, but in those days, pre-RICO, mafia bosses were pretty untouchable from law enforcement.
I have to disagree, almost all of them were sent to prison. Vito Genovese, Carmine Trumanti, Luciano, Catena, Capone, Perscio did time before Rico, and that his leaving out underbosses and others.
