Why did he not get taken out?
Seemed every family that existed back then wanted him dead!
As an "original" of both the historic Mafia cosca back in Castellammare del Golfo, Sicily, as well as a founding member of the American Mafia, and its national regulatory body -- "The Commission" -- Bonanno was way too respected a figure for that.
Despite the hatred and envy some Commission members may have personally harbored for Bonanno, the Commission as a whole would never vote for such a hit. And without Commission approval, hitting any member -- but especially a "official" sitting boss of a Family, was simply out of the question.
