A friend (well you could call him that) of my mother's was in state prison for 11 years. He told me a lot of stories. It's rough shit. The first couple of days he was in there this big black guy came up to him and said he was going to meet him in his cell later that night. Another guy came up to him, and said you know, he's going to come to your cell tonight, and he's going to fuck you in the ass. Do you want that? Hell no! Well, you gotta shank him then. The guy gave him a shank later that day, a 6" piece of metal. When they were in the yard, the black guy was lifting weights. He went up and stabbed him while he was lifting weights. The guards grabbed him and sent him to solitary. He never found out if the guy died or not, but he never saw him anymore.

Sounds like shit out of a movie I know.. I don't even know if I believe it all. But he's definitely got the scars to match.
