I would love to see the school call the cops on some dude who is just showing up to drop off his kids, someone who isn't making a scene, and doing absolutely nothing that could be construed as bad. It would completely expose the administration of the schools as a bunch of pant-wetting ninnies.
Are you suggesting something like a parent dropping off their kids at the front door, in full view of the administration, with a rifle in a gun rack inside their vehicle, or stepping outside the car with a visibly displayed (and holstered) sidearm to assist their children with their belongings?? If so I would support that as a passive, peaceful, non-violent protest against their policies.
