Well, if they’re out of prison, then it’s been decided that they’re no longer a threat to society. Because, in a lot of prisons, you can be kept past your date on certain conditions. So why not let them man a register?
I’m not saying you can’t keep a close eye on them. I’m sure a manager would be doing that. What I’m saying is: in America, society has decided that you’re worthless if you go to prison. We try so hard to keep people from reintegrating into the real world, it’s no wonder our recidivism rate is so high.
