I understand the point here and agree with it. It also feels a bit small and irrelevant to me in the grand scheme of things.

Idk about schools outside the US but at least here, schools already have pretty extensive security camera systems that have the same issues. They are presumably only to be used by first responders during a school shooting or something like that (god our nation is f***ed up) but they do end up getting used in many schools to enforce random rules and stuff that are definitely not emergencies.

There was one time that my sister paid for an apple during lunch but asked the lunch lady if she could keep it so that my sister could come back for it later. She got called in for questioning by the police for "stealing" because the security guard saw her taking an apple after lunch had ended.

There was one guy that was running in the hallway after-hours between two different after school clubs to get information or something like that the other club's teacher. He was talked to the next day about not being in the school after-hours unless he stayed with his club and that even if no one else was in the hall he shouldn't run.

The security camera usage by staff seems like a much bigger invasion of privacy to me but trying to argue about it with anyone inevitably leads to discussions on gun violence because even people for gun control seem to think that the privacy invasion is "worth it in the mean time".
