Really? Is really nobody going to say it?
These people were at a Benghazi movie. Whoever got shot should've known who she was getting into a movie theatre with. It's a risk you are willingly taking when you hang out with this crowd.
OMG that's amazing. I wish we were on AAD so I could like this post.
But in all seriousness, when a "good guy with a gun" stops a mass shooting, the good guy in question is almost always a police officer, a security guard, or a solider. Civilians carrying concealed handguns (or openly carrying assault rifles) are more likely to just be a danger to themselves and others.
