While viewing the film of the school brawl, some parents noticed no adults were stepping in to stop the fights.

Maybe the adults thought if they DID intervene by touching any student in any manner, that adult would be unemployed and possibly locked up in a cell before the end of the week.
At very least, some student would suddenly decided to remember that they had been ‘groped’ by that adult.
This would be a student whose family is hoping to hit the lottery with a big cash settlement.

... some parents noticed no adults were stepping in to stop the fights.
My wife works in a local HS and the entire staff is instructed to NOT get involved.
Let the thugs fight it out and wait for security to handle it.
This is the same school district my wife and I graduated from in '66 ... few if any minorities, no security, no cop sub-substations, no pregnant students, no teachers getting punched, etc. Ain't diversity great?
