Expecting teachers to do what trained officers struggle with? I'm sure there's a better solution.I promise I'm intentionally being obtuse here, but what isn't practical?
It's not a bad start but what if teachers don't want to do it? Not every school is the same. I think we have to start with trained security guards, which I think most schools have these days.
A few teachers in each school could be part of a plan. But you can't require a teacher to do what trained police officers couldn't do. If people want to volunteer, so be it.
But Like I said, it doesn't sound like a practical solution to me.
