That’s my take on it as well.
I think any school that is not locked down with tight security should be shut down until they figure it out.
The day of the Sandy Hook thing, I had some business at a local high school.
My kids were home schooled so I was quite unfamiliar with any security measures they may have had.
I was surprised to be able to just walk in. I don’t remember, but I must have asked someone where the workshop area was that I was supposed to go to. No one gave me a second glance. I was somewhat surprised.
Chances are it’s no better.
