Of course schools teach in the language of the country they are in do you expect them to teach in 5 different languages?!

Over here we have schools which teach completely in Danish and hand out both German and Danish graduation papers, we have schools offering native-level classes in Frisian... Frisians don't really care about more they've always been bilingual. Even more so our Sinti, they don't want to see the language in schools at all but teach it inside the family, they've also always been bilingual. Frankly speaking we're doing more for our autochthone minorities language-wise than we do for ourselves, which would be protecting Low Saxon against the steady onslaught of Standard German.

But, no, we won't start teaching whatever Portuguese just because you arrived here recently and speak Portuguese. Best results are achieved when kids learn the majority language in kindergarten, on the playground, in school, while still speaking their parent's native language at home as that ensures that they're learning both languages properly. It's a matter of experience: Back in the 60s Turkish parents were told to speak German with their kids at home and the result was that the kids learned broken German and their Turkish sucks. That's not just a matter of not knowing those two languages properly as they never learned any languages properly there's measurable developmental delays.

Transposing that to America you should have plenty of schools teaching in native languages. Of course don't mandate everything being taught like that as that would segregate minorities, but things like maths in English and history in Lakota or whatever make perfect sense.

Circling back to black folks: It's high time AAVE is recognised as a proper variety of English. None of that "you're doing grammar wrong", or (in courts) "we'll pretend that you speak Standard English thus not provide a translator, then misunderstand you (tenses and aspects be hard) and lock you up based on that". If a decent number of your students speak AAVE natively it'd also be high time to teach its grammar on a native level, that can happen in ordinary English classes it's, after all, English.

So facial recognition doesn’t work on black people but ai facial recognition can discriminate against them?

Bias in data is always a problem. Take me: I have legs. I'm a man. Supposedly, when I buy trousers made for men they should fit me but all the data that clothing designers have seems to indicate all men are storks so I have to buy trousers for overweight people and then hem ass and waist. And I don't even fucking work out. Soap dispenser doesn't work for you because noone ever bothered to test it on black skin? Same shit just affecting a historically oppressed minority. Personally I wouldn't even call it an issue as it tends to get sorted out very quickly once the bias is spotted, unlike my issue which noone seems to care about because y'all are fucking storks.

As to the police thing: No it's really an issue in the US and it's not systemic racism it's plain racism. Policy makers know all too well that overpolicing breeds crime yet they do it and then say "we need to overpolice even more because black people do so much crime".
