I don't think I've ever heard of a state-level body (in the US) that directly regulates local police agencies. No, voluntary chief-of-police associations don't count. The "blue wall of silence" runs right through them, and they spend a lot of money on lobbyists to help them reduce accountability. State attorneys general can step in when an actual crime has been committed, but seem reluctant to trigger that kind of jurisdiction debate - as in this case, where a crime clearly was committed. There's an old saying that the two groups of people who laugh at the law are those who break it and those who make it, but neither laughs as hard as the ones who are supposed to enforce it.
