How would cameras solve the punishment issue? Aren’t most schools still “zero tolerance” for physical violence?
It should be legally required for daycares to have cameras. Those kids cannot communicate, so there is zero accountability there. And this only becomes a thing because it’s so incredibly cheap to add the accountability.
Obviously, in before times, when it was too expensive, a cost benefit decision has to be made to go with trust only. But now that the cost is trivial, that cost benefit decision has to be revisited.
I hate camera proliferation but, judging by the YouTube plenty of bodycam footage, it does work.
You won't likely find the numbers you want because the very nature of the problem is that cameras make visible something that wasn't.
If the rot is so deep that even who was right and who was wrong does not matter, then that is a separate issue that members of the public need to sort out with each other.
