And why do you think that is?

I'll tell you. I want to see people protected. Can random armed citizens stop a single terrorist at a theater? Absolutely. And for the record I hate gun free zones just like anyone else and believe everyone should carry every single day!
However, do y'all actually think there are enough trained and armed citizens to take down a group of 3 or 4 well trained heavily armed terrorists in an efficient and timely manner? When a Paris style attack happens here only few citizens will fight back, those that do will most likely be out gunned( your pistol against a AK) and the ones called upon to kill the enemy will be the police. I want them ready.
