Well to tell you the truth I don't really have much empirical data about what goes on behind prison walls. I've only repeated what I've read so I'm perfectly content to defer to those who know better than I on the topic.

Probably he will not enjoy his stay. But then, very few do, so as I said, this isn't a replacement for the justice we refuse to hand out ourselves.
