Hoover did go after the Mob for real starting in 1958. Convictions were hard to come by until the application of RICO laws in the 1980s and the Witness Protection Program.
Yet even after RICO was introduced, people like Gambino, Lombardo, Accardo, Magaddino were never hit by it. The government and law enforcement waited until the really powerful figures died out a natural death. They started to fight the mafia only after most of the characters with really gigantic connections were dead.
But why do you say Toodoped is an anarchist?
