Kudos to you man. Through personal experience I unfortunately know too well how hard it is to get legal justice for low-lifes like that. Very creative though, I wish I'd seen the dude's face when he went to pee... I bet he'll think twice before he takes advantage of people again.
As long as you don't rape any of my friends, you're safe from my wrath. That's what all of that was about, I did all the work, except a buddy of mine included weed in the mix he got from his neighbor that lived next door to him at the time. It was simple revenge for raping my at that time best female friend.
