Are the cops whom we all rely on "law enforcement officers," or are they "peace officers"? As historic protests continue across the nation -- and across the globe -- following the murder of George Floyd while in police custody in late May, conversations, debates, and civic strategies are focusing more and more on police reform. What should such reform look like? How would it be realized? How can police accountability be increased in communities across the US? And indeed, how can public trust in police departments be not only restored but strengthened? Our guest on StudioTulsa is Drew Diamond, a nationally recognized expert on community policing and racially biased policing; he's also a longtime advocate for police reform. Diamond served as Tulsa's Chief of Police in the late 1980s and early 1990s.
