True, but that hardly makes us an armed society.
When I think of armed society I think of the way western movies depicts it, everyone has at least a revolver at their side, a rifle nearby, or a shotgun handy.
Mass shooters are cowards. The one who dyed his hair and shot up the movie theaters surrendered as soon as the police showed up. Despite all his gear and weapons he surrendered when he was going to be facing opposition. I really do not believe these cowards would march into a place full of people ready and willing to shoot back.
