the prison system

Early Puritans in our country already built your system in the late 1800s or early 1900s. (I watch a lot of History Channel when I am in places that get reception.) The prison was blank. Prisoners were confined. The entire place was silent. The goal was to let prisoners meditate on their behavior and ways to make it better. Instead, everyone went insane. Self mutilation was commonplace. Not a single soul was fit for reintroduction into society. If you are going to go the path of the twisted and weird, at least do something sensible like Manchurian-style brain washing. Slight torture, friendship, indoctrination, confusion, integration, etc. It would be preferable to let each individual improve (through books, education, and workouts) but if control is your preference then go all out.
