He was there for two reasons: To help guard a car dealership that had been attacked by arsonists the night before, and to provide first aid assistance if needed to anyone who needed it. The rifle was for self defense because guess what, the riot the night before was quite violent, they were even attempting to burn all the cars and buildings at a car dealership can you imagine that? And it turned out that he did need the rifle, because he was shot at, then chased by someone who was armed and threatening his life, then he was stalked and attacked, hit in the head with a skateboard, and managed to shoot the bicep off a man with a pistol who was just about to shoot him dead. In conclusion, go to hell and die in a fire, you commie shitburger.
