Funny you should ask me if I know about the court system, since I'll start Law School soon. My point is pretty simple, if punching a guy because he gave him the finger and because he was "having a bad day", is so "cool" and "badass", then let him state that in court and see what the Judge or Jury will determine. You know what that'll be ??? What anyone with working brain cells would understand ... that it was a really stupid thing to do, motivated by nothing but childish behavior and he has to financially reimburse the victim. Oh and by the way, I hope the asshole only gets $1 because as I stated before, he didn't have to catch Anthrax's set if he was there for Priest or didn't like Bush.
For the n time and to further clarify, I don't support the guy that flipped Bush off, I think he's a retard, but Bush got down to his level by letting it get to him. He didn't had to do the dirt job, he just needed to do like Paul Baloff (R.I.P) used to do back in the day, point out to the other people who the asshole was, call him a poser and let them kick his ass.
P.S. It was refreshing to read your response and notice it didn't include an insult.
