An original ?issue remains; ?why should an audience care? ?Why should they want them to succeed?
Given the negative image of the police in the USA, what can you say about them that would give an audience a reason to be on their side, to root for them? ?They deserve to be fired -- heck, tried, convicted and sentenced to jail for the violations of the law, abuse of authority. ?They are ?outlaws, scoundrels.
What is their implied character arc?
Or do wish to portray them as rogues who by pulling off some 3rd Act heroics are able to get away with their abuses, don't have to fess up to their misdeeds, don't have pay for their crimes?
What dramatic theme are you exploring with these rogue cops, anyway?
