A buddy of mine was arrested for malicious wounding a few weeks ago. He was driving down the road, very slowly due to his grounds maintenance equipment being in the back of his truck, and two guys in the car next two him were making fun of him. The exchange got heated, and at a red light my 5'9" buddy challenged the 6'3"-ish dude to step out of his car and back up his threats. The guy did get out of his car, and after some back and forth words, my friend hooked the guy in the face and broke his jaw. The guy fell to the ground in the intersection, some thought he was dead. My buddy spat at the other guy in the passenger seat, then drove off. As it turns out, the guy had broken his jaw from the impact of the punch.
A few weeks later, my friend got 2 of his friends to visit the moron at work, apologies were expressed, and he was given a lump sum of cash.
That's one way to get out of something like this - basically offer the victim a price he can't refuse. In my buddy's case the idiot took the first offer made and he will not be pressing charges.
But I hope this "Ryan" guy goes to jail for awhile. To pick on a defenseless person with a mental problem is low.
