Great idea, Sheila.
That way, the next time a muderous (but intelligent) nutcase gets into a school, he can deploy the retractable walls and keep the police out.
Then he can hunt down and kill all the defenseless victims at his leisure, rather than just a few handfuls. Hey, maybe he’ll even have time to stop in the cafeteria for a government-sanctioned snack before he liquidates the lunch ladies.
Well, so long as it's nutritious and part of a well-balanced diet. Otherwise Moochelle will be on him like an Obama on a Burger.
