The students and teachers would feel fairly secure once they got in the door. Something like getting on a big plane & being pretty much assured that there won't be anyone with a gun or knife to cause trouble. The present situation is crazy with kids going to school wondering if their school is to be the next to be hit with this.
Really you believe this? I thought you were joking. I've been through a few airports where there were soldiers with heavy weapons wandering around the terminal, check-in security where you're given the third degree, and that gives me the utter screaming nervous shytes.
