I think *some* prison officials set them up to be killed. For example,..this prison put the guy in a cell with a man doing life for killing his girlfriend.
They didn't get along.
At one point the guy says something along the line of, "You cops know how it is. You arrest people that you'd like to shoot in the face".,......and the cop that's interviewing him drops his head and chuckles.
One of my Vo-Tech school students back in the mid-1980's was convicted of sex abuse of his stepchikldren, a girl and a boy. He ended up in Brushy Mountain State Prison in east Tennessee. Brushy mountain was home to the meanest, evilest, most sadistic people in all of Tennessee- - - - -and those are the ones outside the walls. A lot of them worked as correctional officers. The inmates were only skightly less intimidating than the citizens. They would beat the guy to a bloody pulp while using him as a sex toy, let him heal up a little, and do it all over again. I don't knmow, or care if he's still alive these days, but the world would be a better place if he isn't! Jerry
