Kyle decided to be there. He had to travel miles to get there. He stayed there to "help protect" a local business that he has no connection to for hours. And he stayed for several altercations before holding his hands up as he walked past the cops.
For me, you don't get to start a fight and then claim self-defense. If you don't want none, don't travel several miles, cross a state line, and hang out at a local car dealership then go patrolling along the protest area with a gun and you won't get none.
