Stay away from them. Being anywhere near them can get you into serious trouble.

He could have killed a patron or a firefighter. You need to turn him in, let him get what he has coming. If he put ketchup on my seat, I'm pretty confident I have ways of making this kid pay and getting away with it. Sounds like he needs a broken rib or jaw. or better yet, call the police.. He needs jail time.
That "friend" has NO sense of respect. He's reckless and honestly he's going to end up dead or in jail if he doesnt' wake up. I'm sorry to say it, actually I'm not. If he doesn't change you can mark my words..."Dead, or in Jail".
