As I reach for what the hell specifically drove that guy to clearly panic and draw his firearm and shoot, my best guess is he saw the gun and then saw a hand pull it. His two brain cells failed to understand it was one of his own pulling out the gun and opened fire thinking the guy just pulled his gun.
