I would disagree that there's any problem with this outstanding show. The cops it depicts realistically have their flaws, some of them are in fact unlikeable but others, despite some venal tendencies really end up doing the right thing for the right reasons. Welcome to real life and to most big city police departments.
Specifically, the young rich cop and Regina King (the black detective) IMO are both quite likeable because their ready defaults are honorable.

"No we have our FRANCHISE QB and I want to keep him rather than get 2 guys who may or may not be productive NFL players.
Palmer's situation is different and if I had my choice between Palmer and buttfumble, I'd take buttfumble"
