This is probably the most sensible idea I’ve read in regards to how to protect schools, and that may be politically achievable. Talking to Bitter tonight, I’m struck with how many things you may typically find around a school classroom that may double as weapons. Standard dry chemical fire extinguisher? It can make a great improvised defensive spray (don’t ask me how I learned this). Do you remember those pointy wooden sticks teachers used to point to the chalk board? (do they still have those?) Some of you might be old enough to remember when teachers did use them as weapons. :) Anything heavy, like a chair, is an effective bludgeon. When I was 16, I was given a 4D Maglite to keep in my car, along with instructions as to what its true use was (and it wasn’t, necessarily, illuminating the engine in the event of car trouble, though it was useful for that as well).
Point being, and mirroring that of the article, we spend a lot of time and money drilling against outbreaks of fire, which at this point is now more than paranoid, as no child has died in a school fire in half a century. So why not get teachers in the right mindset for resisting school shooters? That doesn’t necessarily have to involve arming them with carbines or handguns. Much can be accomplished just with mindset alterations. And, after all, that is part of moving the culture in the right direction.
