The problem with many of these "structural reforms" is that they are very susceptible to capture by police unions. Take for example civilian complaint review boards - often appointed by the mayor. Except the mayor often relies on police unions for votes - and they care who is on that review board - where as the typical person (I'm including myself) doesn't even know if there is a review board, let alone who is on it.

Definitely think it's a step in the right direction - but think more time needs to be spent ensuring an "adversarial" relationship that is not prone to capture.
