To clarify something, "The Hook" was a name given to LaPietra by the media. Most called him "The Bull" on the street or simply "Ange." The media created the nickname of "The Hook" because so many people would say "Ange has me on the hook." It has nothing to do with torture or hanging people from hooks or any Chuck Goudie wet dream. It means you are "indebted" to Angelo...he got his "hooks" into you or your business.
If the La Pietra torture stories are made up, then who was the most sadistic of them all in reality in your opinion? I mean, somebody has carried out the Action Jackson murder and the Accardo home burglars' murders. Who is generally thought to have carried them out?
