Lefty personified the old school Code of Honor more than most Mob guys. When the news about Pistone broke, he refused to rat on anybody,and caught a 20 yr sentence. He served about 13 and due to his health,he was released. Originally he was on the "Hit List",but since he kept his mouth shut,he got a pass.He only lived about another 2 years after getting out,but even to the end he refused to talk about his Mob associates. He even turned down a huge amount of money,(some say up to 1,000,000 ) to do a promo interview for the movie. Reportedly,on his deathbed,he threatened to spit in the faces of the producers if they brought it up. He could have taken the money,wrote a book like Pistone,and retired comfortably....But maybe the most important reason that he didn't snitch was that his family would have to live with the shame of his betrayal, and would've lost their honor. I believe that, regardless of the sentence that he could have gotten, he would have done every second and never give the Feds the satisfaction of flipping him.
