Doesn’t matter - TM attacked GZ. He got more than he bargained for. Thought he was a tough guy. Found out he wasn’t.
It’s really really simple: don’t assault people.
Agreed TM got more than he bargained for. Unfortunately for GZ he has been dragged through the mud and may be unjustly imprisoned for his actions. If he would have stayed in the car this event would likely never have happened.
