Police unions as they currently exist are definitely a problem, but they are far from the only problem.
Institutional problems also exist, like the prosecutors that hold the police accountable also work with those police officers and rely ln them in other cases, and the fact that police are highly discouraged from and often times actively punished for speaking up against the actions of other officers, and the fact that they are massively over-trained to use force and not trained to recognize non-criminal mental problems, and the fact that the laws that caused there to be "a lot of poor blacks" as you call it were directly enforced by the police (you can tie a straight line from slave patrols to modern police departments).
There are a lot of poor blacks because they're a historically poor community and breaking generational socio-economic trends is hard. Historical racism played a large role, but it's the frosting, not the cake.
Tying racism to police departments is an odd non-sequitur, police are ubiquitous across the world and historic racism is not a good reason at all to defund the police.
Police are underpaid and undertrained, that requires funding, and more funding, not less. That, combined with the unions, largely explains why there's a dearth of talent and subsequently poor results. Unions are the death knell of meritocracy, and without hope of advancement, talented individuals focus elsewhere.
"Blue-wall" criticisms are largely a function of lack of proper oversight, and again, we end back up at unions. Prosecutors are in their own bucket, so I won't lump prosecutorial reform into this thread.
