It’s always the first thing I imagine when people try to sell me on the “good guy with a gun” scenario. If a shooting at a mall breaks out and a dozen people from all over the mall draw their concealed piece and start to John McLain’in around, how will anyone know who’s the bad guy? What do they imagine the cops will do when they blitz in and see them skulking around or hunkered down with their side arm, or actively engaging with someone? What if the shooter fires off before escaping into the hysteria and leaving a bunch of dudes chasing their own tail? The opportunities for life and death hijinx are terrifying
