Since this is always the lame response from the anti-gun crowd let me clue you in. Also, interesting screen name considering what you typed.
The gunman opened fire here because he knew guns were not allowed....it has nothing to do with everyone being armed. Go ahead and post a story about gunman shooting up a gun range and I'll take what you just posted seriously.
I could allow an armed security guard or a number of them at a location and a gunman will be less likely to choose this location over a gun free zone because the chance for static is much higher. It's not about having the secretaries walking about with 9 millimeters. Only armed and trained individuals. This is the type of logic regarding gun usage that won't get covered in the media, so you have people coming up with the garbage you posted.
I don't support maniacs shooting up theaters...tends to be a white thing anyway....but I don't follow this anti-gun stance among us either....and it's mostly from folks who have never even been near a gun in their lives as far as usage...hilarious...get your honest and strong opinion from others, brehs!
