James Holmes’ attack on a packed Aurora, Colorado cinema was planned for maximum carnage, and planned well. The 24-year-old entered through the right exit door wearing a bullet resistant vest, a ballistic helmet and a gas mask. He tossed tear gas canisters into the dark and then opened fire on the crowd with a shotgun, rifle and two handguns (although in which order and with how many rounds we don’t know). It’s hard to imagine that an armed civilian could have done much of anything to stop the carnage. Unless, of course, the law-abiding citizen had encountered, challenged and possibly shot Holmes before the attack. And anyway, who wouldn’t have wanted a firearm inside the cinema, not knowing how many attackers were involved and how the killing might proceed. Mayor Bloomberg? We know how his bodyguard roll, and we know Bloomy doesn’t roll without them. So isn’t it always better to be armed than not, no matter what?
