Hm... it seems like a more of the NRA efforts to have armed guards at schools aren't going so well. A "gun safety expert and fire arms instructor" promptly left his guns unattended in the school washrooms shortly after being hired. If an "expert" can make these type of mistakes think of how rent a cops will treat weapons and how long it'll be before accidents happen.
