This is a very common pattern; my university pushed through a ZeroEyes AI camera/open carry weapon detection contract within 2 weeks of a shooting at a nearby school, even though it’s trivial to bypass by hiding it; it’s most probably just (gruesome as it is to think about) a bad press insurance so if anything happened, they can say they had “state of the art AI detection” and they did all they could. No one wants to be the one caught not doing “all they could” against the media cacophony in the immediate aftermath.
