Here is another point of view. Let’s deliberate on the issue rather than label as “stupid” or “crazy”.
Was the first fire drill called crazy because it might scare children when in fact there was no fire? Maybe.
We are involved in a war with Islamofascism that considers shooting school children fair game. We also have the occasional nutcase who wants to shoot at the unarmed and defenseless. What is so wrong with preparing for such scenarios by drill? Or do we allow Americans to experience terror for the first time only in a reality situation?
Why is the idea so stupid? What if the children learned something? Or has that also been outlawed in schools so they only learn some sanitized myths about the real world.
BTW, far from encouraging some liberal aversion to ownership of firearms, I would guess that most children who experienced even a practice scenario would realize the necessity of arming oneself. Experiencing the “bad” things in the world is often a cure for the “head up the as” world view that we often tag as a liberalism.
Sixth graders are old enough to learn that the shootings on TV are sometimes real. Prepare for it.
What would have been appropriate is for one of these kids to have taken a .38 out of their lunch box and fired a round through the “hooded idiot teacher” pretending to be a gunman threatening to kill these students.
