One of the huge problems in schools, as well as in cyberspace is bullying in social ostracism (shunning etc) as well as beating. It trains people to 'shed water' in their actions. Surrender to bullies, yield to their demands and otherwise 'toady' to them. Anyone who objects or fights back feels the weight of the online or schoolyard pack members.
This is, I feel, exacerbated by the relentless increase in the cost of teacher oversight. The use of teachers is an abuse of their role as teachers. They need a class of staff - watchers etc. There were often student monitors when I was young to supplement the misuse of teachers in lieu of employed as watchers.
What is the solution? There is a need for the halls/stairwells/yards to have a watcher present on each landing, hall segment, entry, exit and all corners of yards/approaches.
This is a lot of people to add to the budget = it is neglected, this is why they stopped using teachers $$.
The only solution is remote watching with a central operating room. Sounds like China? - not so much. China has a hated government, as recent riots show.
There is an old adage, 'In loco parentis'

What we see in unfolding in schools (and in our neighborhoods) is the same sort of structure engendered by a lack of supervision by 'Parentis' over various groups.
So we must assert control in schools/yards/neighborhoods/online to the degree needed to limit the levels of oppression exerted by peers/cliques/gangs so people are free to go about without some one/gang/clique wanting to exert control.
So if we put 4K cams in schools/yards/halls with a watch room - is that OK, what if we have 'true Parentis' watching this stream as well as staff members? If Johnny bullies Lenny and one of the parents tells Johnnie's parents - who looks at this later and chastises Johhny - will this work? Will he not care = it's a jungle, he has to 'man up' a Lord of the Flies response?
The same thing plays out in many schools/cities, the hordes of students and gangs and street people are a large LOTF experiment.
This HAS to be solved.
To what degree do other countries have this problem?
