From what I've read from multiple sources Franzese was never found guilty of rape, apparently he never even was arrested for it and only was accused of it in 1947. Plus we also know that the government had a tremendous hard-on for the man. They couldn't get him for all the murders and stuff, so they accused him of a lot of things he probably never did, like that bank robbery for instance.

I'm not saying that Sonny was some kind of hero at all, far from it. He committed countless murders and acts of violence, but he did it in a world where there were different rules and regulations than in normal society and because of that I judge/look at him in different light than the killers you mentioned before like Ted Bundy and Pol Pot. And I truly believe that this doesn't make me a mob apologist, I'm just someone who's very wary of painting everything/everyone with the same brush.
