Worth noting that as a grad student, Saul Alinsky, chose to hang out with Frank Nitti and the members of the Chicago Outfit to study their organizational power structure. Nitti was, of course, the immediate successor to Al Capone after the Big Fella got sent to the penitentiary. Not surprisingly, Alinsky became an extortionist. His protest methods were much like those of the Mafia.
I forgot that. That was news to me.
