The neighborhood I grew up in was in the near suburbs of Nashville, close enough to downtown that we were annexed into the city limits while I was still in elementary school. When I was a kid in school back in the ’50s, the doors to the schoolhouse were unlocked from about an hour before class started until a couple of hours after school was out. School violence consisted of a couple of kids squaring off at recess. Most homes had guns and one or more veterans (WWI, WWII, or Korea) who knew how to use them. We kids plinked in our back yards and in the woods with our BB guns.
And no one worried about whether of not we were safe at school.
I suspect that our present school safety problems have a much more profound cause than the politicians are willing to confront.
