I had an art teacher in high school who often
tippled from his thermos. Presumably it was coffee but, trust me (I checked), it was wine (a
rather cheap one at that). He was a great art teacher but, frankly, he would be the last man on earth that I would ever trust with a gun or weapon of
any kind. That said, on a case by case basis, it would be hard to justify arming teachers. To be honest, arming teachers would only precipitate
cases of teacher against student violence. It's not a stretch to imagine an overwrought teacher, trying to maintain control, losing "it".
Granted, its been a long time since I was in high school. I was a part of the class of '71. Yet, even at that early date, weapons in school were
allready a problem. To that end, the school board had metal detectors installed at the main doors and everyone had to pass through a quick
inspection. Yes, it was intrusive (the kids had to work a little harder at bringing in their "contraband") but, for the most part, we all felt a
bit safer.
As far as securing a college or university campus, greater challenges must be met. But, where possible, some basic security improvements could easily
be instituted. After all, one really doesn't know when, where or how an irrational act of violence might manifest itself.
