I remember when I was in college & university, the US Bureau of Prisons used to come to my campus job fair every year. When they found out that I was putting myself through school by working in fast food (and lots of loans), they tried really hard to get me to hire on as a kitchen supervisor over a crew of inmates. I wasn't ready to work with inmates carrying knives, so I declined. Since I was studying management, if they'd had more managerial positions, I might have considered applying.

Though I now know that I wouldn't have lasted anyway. Years later, I participated in a few hours of prison ministry and it was one of the most frightening experiences in my life ... none of the inmates threatened me in any way, but the whole environment--including the "we have no obligation to rescue you if something happens" agreement that I had to sign in order to participate--was innately threatening.
