> Gun and weapon detection is still useful to stop shootings and stabbings that arise out of fights, where one member may suddenly present and use a previously concealed weapon.

Which might be a reasonable thing to aim for? It was mentioned up thread there's >100 school shootings/yr. The vast, vast majority (>>90%) of those are not the "crazy person randomly shoots up school" type, but rather the "two people in a fight / two groups in a fight / targeted revenge on single person".

The former is tracked as an active shooting incident, by the FBI. In 2023 there were 3 such incidents: https://www.fbi.gov/file-repository/2023-active-shooter-repo... (10 year average is a bit higher).

Of course the downside with the latter is that simply weapons checking at the school won't stop it from happening right before / after school, or otherwise outside of school.
