I went to a HS taught by Jesuit Priests. A lot of these guys were veterans. I think about 1/2 of them were boxers when they were kids. God help someone who tried to hurt one of their flock...literally God help them. Some of the best people I ever met. Stayed in touch for many years after.
My son's HS has a full time officer assigned. She has a small office near the admin center. Keeps the patrol car parked out front. Keeps her long arms secured in the vehicle. It would not suprise me in the least if she had one secured inside. Nice lady but let's just say I wouldn't want to come home late w/o a good excuse if we were married
Kind of a "looks good kill" demeanor without trying.
