Cincinnati is often cited as a model for other cities looking to establish police oversight boards. CCA Executive Director Gabe Davis says the city has a nearly 20-year head start. "There are a lot of other models out there for how to do this work," Davis said. "We are unique in the sense that we have an investigative driven model. We're not there just to audit what's done by the police, but really there's an independent investigation with independent resources to do that. And that is quite unique, there are only a few jurisdictions that have that kind of structure."
