Another depressing thread. There isn't enough money or resources to provide full time security at schools. Not only is it not cost effective, but it is just not necessary. People have to be able to defend themselves. That is all it takes. That's it. Extremely simple. Right now, it is impossible to effectively defend anyone at a school, even yourself, from someone armed with a firearm. Once people are allowed to defend themselves at schools again, this problem will go away.
