In the aftermath of the Aurora movie theater shootings we have heard a lot of people saying that the moviegoers should have been armed. Now, I'm not an opponent of the second amendment by a long shot, but saying that people should go to theaters (and any other public venue) armed raises questions. If everybody starts packing a gun to the theater, how will we know whose guns were brought there for the purposes of self-defense and whose may have been brought to kill innocent bystanders? If you go to the movies with your children, will you sit right next to a guy who is openly carrying, without knowing for certain what his intentions are?
What if a man wearing Muslim garb walked into the theater carrying openly...do you think people would want to sit next to him, let alone allow him through the doors? Remember, though, that Muslim citizens have the right to carry, too. What if the man looked like a skinhead or was black and wearing one a (gasp!) hoodie? Would you still feel safe sitting next to him? What if he resembled James Holmes (without the freak hair), Anders Breivik or Timothy McVeigh?
Pro-second amendment or not, I'm no more likely to want to sit down in a theater knowing someone has a gun than I am to get on an airplane with them.
