First thing you hear is more gun control! What if one teacher or one janitor would have been armed. This nutcase may have gotten a few people or maybe none if someone had a legal firearm.
It is our responsibility to defend the weak and the innocent. I think all who can should carry a firearm, trained and ready to defend those who need defending.
How many more tragedies must happen at a “no gun zone” before we pull our heads out of our butt.
You can’t legislate away crazy, but you can defend against it!
