Back to the Drawing Board?

Rocks and tiny symbolic baseball bats vs a mentally ill person with an AK-47 assault rifle. I hope I'm not alone in seeing the tragic absurdity of this picture. Nothing like preparing teachers and young minds for a horrifying experience. Kudos to a Hail Mary attempt to do something about an intractable problem, but creating a constant reminder to very young minds that a person could come to their school at any time and attack them does more harm than good. Trying to explain to children that they need not worry about being attacked because it probably will not happen is futile because children do not understand probability in a mature way. Reminds me of the times when I and millions of other kids spent too much time in a ball underneath our school desks which, though debatable, might protect us from a nuclear bomb.
