Well that depends on your definition of smart.
I've encountered numerous science/technology PHD's that can't handle simple logic like, oh, I don't know, making sure something is plugged in?
It makes me laugh when people say this will help violence and gun free zones are bad because if someone else had a gun they could have stopped it. When that moment comes 90% of people would either freeze and not shoot the other person or still hide. I've seen plenty of trained people freeze up when they've actually been put in the situation to shoot a person vs an animal or a target. Shooting a person is much different. Most people who carry just have a false sense of power but put in the spot things change fast and that power disappears fast. Trust me its not easy to pull that trigger even when your life us in danger. I am 100% for ownership but carrying at school only means you're a p*ssy who should be focused on grades instead of the metal p*nis in your pants.
I would be more in favor of a system where only administrators and teachers can carry on campus.
