When I was in my early twenties, I took my young family several times to a neighborhood theater at a nearby shopping center. It was a rough neighborhood.
Whenever something exciting happened in a movie, the whole audience would erupt into gleeful screaming, yelling, laughing and jumping up and down. It was hilarious! The second time we went and thereafter, we joined in. It was a hoot!
Many people in the theater carried weapons. It was a fact and rule in that area, that nearly everyone carried weapons. There was never a shooting in that movie theater that I know of.
Maybe some classes of people are simply more clumsy with tools and mechanical devices than others.
The guy was drunk. I'm pretty sure concealed carry while intoxicated is a violation of the permit. This moron needs to be made an example of. If you are going to concealed carry, you'd better take it seriously. Drunken jackasses fumbling their weapons and shooting innocent people are exactly what the opponents of CCW warned us against.
