well, let's break down this potential problem on deranged gun-toting wacko at a school.
Is being deranged a problem? It sure can be. In some cases, people who are clinically insane are removed from society because their insanity prevents them from functioning on their own.
Is gun-toting a problem? I think most of us here would agree that the mere act of carrying a gun is not harmful in any way. So, no problem here.
Is being a wacko a problem? That's such a loose term that it really doesn't mean anything anymore. So, I'm ignoring it, because any clear mening would make it essentially synonymous with "deranged."
Is being at school a problem? No, clearly it is not. Lots of people do it all the time.
So, if gun-toting is not a problem and being at school is not a problem, why would there be a problem gun-toting at school? Answer: there wouldn't be.
Your scenario revolves around a lunatic, (assumably) bent on killing people. This is not a good starting point for determining regulations for people who are not homicidal lunatics. It's a little bit like saying "rabid dogs sometimes bite people, therefore all dogs must be caged 24/7." Why treat the healthy dogs as though they are rabid? It doesn't make sense, unless the goal is to cage all dogs, which sadly, may be true.
