No where did I call the state of policing good for everyone. I said it's the "tip of a very long spear", by which I meant that the underlying root cause of racial inequality goes back a very long way, and until we address those causes no amount of police reform is going to make our racial problems disappear. I'm not sure what can, but I think that a prerequisite is access to the courts, which poor people in general and black people in particular just don't have. I can sue if a cop roughs me up, because (A) I have money, and (B) I'd more than likely be looked at as a credible witness. Without both of those the court system will get you nowhere. And if you don't have access to the courts, the cops will continue to act however they want. There are too much data out there about how shitty people act when there aren't any consequences to think otherwise.
(As a digression, when I was 16 I was a witness in a case in which the cops had broken into a buddy's house and then charged him with a bunch of drug stuff. After my testimony, which I'm sure was horribly weak since I was 16 going against a career prosecutor, the judge (it was a bench trial) openly said, "Ok I'm not considering your testimony." It was pretty surreal. But in the court's eye a good witness looks a certain way and bad witness looks another way. You can be a good or a bad witness of either color, but it's orders of magnitude easier if you're white.)
I'm 100% in favor of police reforms, hence my comment about union busting, which I wouldn't make about any other government union. I just think that you can't willy-nilly abolish departments, or even make everything seem like the cops' fault. It will get you no where. What black people need more than anything is intergenerational wealth, which the New Deal made possible for many white families, while "legally" excluding blacks (and when black families tried to sue after the passage of the Fair Housing Act the Supreme Court was like, "That was legal then so you didn't actually suffer any reparable harm."). Again, definitely on the side of reforms, but they will be hollow without much deeper economic justice. That's a way bigger problem to solve, so I guess I consider myself pretty pessimistic here.
