Try to be better.
There is no excuse for what this moron did. Don't defend it just because it's something you perceive as a "cause for lefties." What this man did is pathetic.
Did the police charge him with anything? Did he get indicted? Was he tried? I am not sure I want to defend what was done unless we want to play the ASSumption game.
If he had not pulled out a gun, would the much larger and stronger dude have stopped assaulting him?
