The response to the evil loser in Nashville has been predictable in just about every way.
Including the observation that the only way to stop these things in their tracks is armed people among the things you want to protect. Children and employees, in this case.
And the outcry from the anti-gun bigots is the same as always. "A gun did this and you want more guns? You want to arm teachers instead of taking the guns away from everyone?"
I'll just say what I've said in response: If you don't trust someone with a gun, you shouldn't trust them with your children.
If I don't trust someone with a gun, I don't trust them. Period.
