Give those kids some training, and pretty soon, any person who wants to take down a school is going to face an army. And no, I don’t want a society where kids form armies for their own survival. But we already have a society where kids go to school and get killed. Regularly. So personally, I’d choose my kids being in an kid-army in their classrooms, bonding with their peers, knowing how to take care of themselves, and knowing that their friends “have their backs”, far more than I’d choose my kids being trained to be helpless, in a society that so readily arms killers.
