According to Life Magazine, Giancana forced Accardo to give up the Outfit by shooting a bullet over his head.;

But again, I'll never understand how The Outfit trained a legion of sadistic torturers, which New York never saw many of. Thanks, TonyG. According to the article, they chained people to a stretcher and pulled the chains out until their joints popped. Are there any examples of this? I'm curious to know if the bosses were ordering torturing, or the soldiers were just going wild with bloodlust.
