What's the point of these drills? It's not like the cops are going to go into a school with an active shooter and stop him. They'll just wait outside while the children get killed and hope the shooter kills himself like in every other school shooting. Or maybe they like to practice murdering teachers and other innocent people since they think it's part of their job? Seems pretty insane the school would let them carry out their sick fantasies this way.
