Damn man, that sucks. I got charged for manslaughter after knocking a guy down and shin checking him in the throat after he swung at me. But it was plea bargained down to aggravated assault. Anyway, just be careful about fighting. You even have to be careful defending yourself, you can be charged if they determine that you used "more force than necessary". The best way is to just avoid physical conflict altogether.

Anyway, hope you don't get caught up in the system....the system is indeed a bitch.
