I'd just report the guy to the police.

I really have trouble understanding Uchess' leniency. I am more inclined to be lenient to strangers when they intentionally try to harm/steal/insult me in any way. People are generally assholes anyway, so it is kind of expected. However, if a "friend" does that to you, I consider it betrayal, and betrayal is probably the worst offense in my book. I'd kill that bastard if I could get away with it.
