Isn't it odd that there is never a good guy with a gun there to stop the shooting.
In this case they got, "lucky" that a Police Officer happened to be on the scene and took action to neutrilize this miscreant or many more would have died.
The good guy with a gun is as elusive as bigfoot when you want them to show up.
In any case, with your reasoning, there were no good people in the mall at the time of the shooting. I guess that includes the dead people. Hopefully, you will someday meet a good person face to face. Provided of course, that you get out of the garage once in a while.

There are some lively and interesting conversations going on regarding criminals shooting innocents. They always pretend and claim to be about saving children. They always don't care about saving children, just banning firearms. So here is the challenge. Are you for doing the things required to eliminate threats and hazards to safeguard and protect the lives of children? All the things required? Or are you just out to ban firearms and using children to further your cause. We already know the answer but go ahead and pat yourself on the back anyway and claim you are all for the children. It's what you hypocrites do best.
