Perhaps you’ve seen this story about the woman who shot the man who ran into a movie theatre with a gun? According to this public Facebook post by Realtalk:

On Sunday December 17, 2012, 2 days after the CT shooting, a man went to a restaurant in San Antonio to kill his X-girlfriend. After he shot her, most of the people in the restaurant fled next door to a theater. The gunman followed them and entered the theater so he could shoot more people. He started shooting and people in the theater started running and screaming. It’s like the Aurora, CO theater story plus a restaurant!
Now aren’t you wondering why this isn’t a lead story in the national media along with the school shooting?
There was an off duty county deputy at the theater. SHE pulled out her gun and shot the man 4 times before he had a chance to kill anyone. So since this story makes the point that the best thing to stop a bad person with a gun is a good person with a gun, the media is treating it like it never happened.
Only the local media covered it. The city is giving her a medal next week.

There are a few inaccuracies in that story, according to this Snopes analysis. First, it was Sunday, December 16; there was no Sunday, December 17. Second, he didn’t shoot his ex-girlfriend. Third, it is offensive to say this is anything like the Aurora shooting because it was not premeditated and he did not go in with military grade weapons and ammunition to wipe out a whole theatre full of people. Fourth, there didn’t just happen to be an off duty county deputy at the theatre; on the contrary, the deputy sheriff was on duty as an armed guard employed by the theatre. She was doing her job, and she was thankful for the years of training she had received in using a firearm to disarm a perpetrator. This was not just a moviegoer with a gun.

The most important takeaway from this story, for me, is that the woman who shot the perpetrator was literally “on guard” and had years of training firing a gun. It seems the pro-gun people would like you to believe we would all be safer if everyone had a gun. It’s not that simple. See this video if you think all you need to do to protect yourself and others is to buy a gun and go to a shooting range once in a while:
