It's kinda funny. On Wednesday, I'll be showing a video in physics class. It's an experiment/demonstration that, extremely unfortunately, I wouldn't be allowed to do in class. The demonstration is measuring the velocity of a bullet. Extremely good physics. And, the demo is taught by an outstanding professor from MIT.
I also have a print out of a news article regarding a high school teacher who did a similar demonstration in a physics class. They were talking about filing felony charges on him for possession of a weapon, plus charges with endangering the lives of the students, etc. At the bottom of the article are comments, including this wonderful quote: (which is applicable to the story in the OP of this thread)
?A fear of weapons is a sign of retarded sexual and emotional maturity.?
?Sigmund Freud
You don't know how much I'd love to have a .22 in class to do a classroom demo for determining muzzle velocity. Experiments like that are incredibly engaging. (Today, for my final review of motion in 2-D, we did a ballistics lab. Water balloon slingshot. 4 vertical (90degree) launches, some stop watches, then pulling a random angle out of a hat. Students had to calculate where the heck I needed to stand for their assigned angle. I was absolutely soaked at the end of class, and took several shots to the head. Hurray to my students.
