I saw a bunch of what looked to be junior high kids having a paintball war in the cemetery in town here this past summer. SWAT was not called out and as far as I know nobody was killed. When we were kids it was BB gun wars. Paintball guns didn't exist yet. Nobody got killed then either
My son and a bunch of his friends used to camp out at our farm and spend an entire weekend shooting paint balls at each other. I knew where they were and they were out of trouble. It was a great time for them.
