A teenage boy rapes and murders his best friend. Locked up in a psychiatric hospital for years until he is deemed "cured". At that point he is allowed back into society AND to attend my school. Well, I saw him today. Long greasy hair, black trenchcoat, scowl on his face, carrying a butchers knife. Ok, actually, he was wearing jeans and a golf shirt, a cellphone on his belt. He looked like any other guy. That's the scariest part.
