Two similar stories, two different outcomes.
The first story comes from my own school district, where almost 4 years ago a middle school student took a loaded .22 caliber pistol to school and was going to shoot his science teacher. Law enforcement was called. A sheriff showed more restraint than I would have when the boy raised the firearm at him--I'd have shot the kid on the spot. Here's what eventually happened to the boy.
Apparently they think like I do in Longwood, Florida. And unfortunately, that kid only had a pellet gun that looked like a 9mm pistol. I used to have one of those b-b pistol/pellet guns when I was a teenager.
We didn't take firearms to school when I was that age.
