Who needs guns when you can make bombs right in your kitchen?

The gun genie was let out of the bottle a long time ago and he isn't going back in no matter how hard you try. As long as the crazies and crooks have access to them, and they will be the ones who find a way to get them even if they are outlawed just like anything else that's outlawed, the only really rational thing to do is to protect yourself. Just one sane, armed person in that theater may not have taken the guy out with all of his body armor but he could have been slowed down enough that more people may have escaped. Nobody wants a shooting gallery (except of course the afformentioned crazies and crooks)but bringing a box of popcorn to a gunfight definitely doesn't work out so well.
