Just to be clear: what we are looking at is a concerted and coordinated criminal conspiracy to cover up a range of activities including murder.
a concerted and coordinated criminal conspiracy Yes. It's Chicago. You've just described city government in six words.
But just as life-destroying are the things that go on in smaller communities, where talking about conspiracy is just as valid, but the stakes, departments and communities are smaller, so it doesn't get as much attention. I know from personal experience that small town cops can be just as awful, and power structures in small towns don't get the same push back as they do in larger places.
I'm pretty sure we are seeing the beginnings of a sea change here.
Citizen surveillance tech has reached the point that the behavior of police can't be ignored any more, and the disconnect between law, policy preferences and "rough justice" as actually practiced is shocking to people who lived comfortable enough lives to not notice before[2].
Prosecutors and especially judges, always slow to change when change makes their jobs harder, will take longer to get used to the notion that wink-and-nod isn't going to work any more. Police unions are going to lose this fight, especially as activists are starting to become savvy to the tactical advantage of splitting Republicans between law and order fears and union busters.
The result, at least hopefully, will be police that, if not actually part of the community again, are not able to function as the biggest gang around with legal cover.[3]

[2] Not casting any aspirations there; we all pick and choose where our outrage lands to some extent, I'm just as oblivious to some injustices as other people are to this. It is simply human nature to worry about things closer to one's self.
[3] Not all police, some of them are very good at what they do, etc. At least we can retire the "few bad apples" deflection.
