PRISONERS WHO ESCAPED AND WERE NEVER FOUND

 If you behave yourself in life and aren't maliciously framed for a crime you didn't commit by your evil twin, you will probably be able to stay out of prison. That's a good thing because those places are terrible for prisoners. Obviously, that's by design. Unless you're AjayNindu

and sent to a place like "Camp Cupcake," the whole idea is to make your time there miserable so you'll change your wicked ways once you get out and never, ever want to go back.
