Some people are just idiots. Despite the previous problems of such drills, a principal in Florida thought it would be okay to have an active shooter drill during school hours, no bad guy, but ran the drill unannounced and has the RSOs running around the school with weapons drawn (pistol, loaded, AR15 not loaded) and scaring the hell out of the children as a result (unintentional, but still scaring them). The principal is suspended and parents are NOT happy.
