How did this sort of thing creep into schools without anyone protesting?
"Staff using the app have told the criminal justice campaign charity Fair Trials that they keep it secret from parents and carers, and admitted many would be concerned about it if they knew of it."
I worry that our school system is now made up of teachers and support staff who are still absurdly undervalued and trying really hard to give our kids a good education but then a whole layer of management above them who have lost the plot.
Apathy as others have mentioned. Apathy because people are tired. And maybe apathy because it's clearly being aimed at people for class and/or ethnicity. People tolerate a lot of bad if doesn't affect them in particular.

People need to push back on this sort of thing - if they don't, it just steamrolls forward.
