I remember watching a documentary about the American and Italian mafia narated by Ray Liotta. Henry Hill was interviewed and claimed he was sitting in a bar one day drinking and Gotti came in and brutally beat a guy who owed money to him or the Gambino's. Hill said there was blood all over the place, but he don't know whatever happened to the guy, if her survived or not. I found Hill to be totally unbelievable, and I'm not sold he even ever met Johnny Gotti.
