Lefty Rosenthal probably had the best deal. He never had to hurt anyone. Just had to keep business rolling at the mob owned casinos. They wanted him to look as legitimate as possible. He evaded prosecution and somehow ended up surviving the killing spree that took place at the onset of the skim trial. Spent his golden years running a restaurant in Boca and continued to mop the floor with bookies who didn't have half his sports knowledge. The only real long term comeuppances he faced were that he ended up banned from Nevada casinos, which killed him (he tried several times to sneak in with disguises), and of course his marriage to Ginger McKenna, but that was his own personal doing.
