As a retired teacher, I've been trying to imagine the teachers in the school where I taught having guns. I've been thinking about how it would feel to be issued with a firearm and some ammunition, and told to practise, ready to use it in the event of attack. I've been picturing this item, perhaps kept in a drawer of my desk, or maybe even on my person in a specially-provided holster. I really have been trying hard to imagine this.
But I can't.
