I know I’m behind the times, but I was surprised recently when, at an elementary school in the US, they showed me painted lines on the floor of the classroom, indicating the zones out of the line of fire for somebody shooting through the small, jail-like window in the door… apparently they train the babies on this.
I wonder what led up to a system like that—overcompensation for a really big mistake in the past? Abstract fears? The genuine wishes of the parents?
(Edit: looks from sibling comments like this [the pickup line technique] might be a hangover from the excesses of the COVID times…)
