Did you even see the last 2 seasons? They actually really confronted those issues and outright said that they weren't really the good guys, the show tackled multiple times that the system is completely broken. I get if it was Law and Order being mad, but man you're mad at the only cop show I've ever seen acknowledging and trying to tackle these issues. I mean, that's literally why they made the captain gay and black, and that's just one example.
