Now for my second thought. If these places aren't going to get rid of their "gun-free zone" status, despite the overwhelming circumstantial evidence that they simply get more people killed, then how can they improve their security where it actually make the people inside safer?
I have a few ideas. And for the sake of simplicity, I'm going to apply them to a college.
First up, they need to absolutely control access to campus.
This sounds like a lot of work, and it is. Luckily, we don't have to start from scratch -- a lot of the preparatory R&D has already been done for us.
All we need to do is take the existing plans for maximum security prisons and convert them to college campuses.
That, it seems to me, is what it would take to set up a truly safe "gun-free zone." Anything less just makes these places little more than hunting preserves for psychos.
As was shown at Virginia Tech.
And the Omaha mall.
And Northern Illinois University.
And who knows where next?
