FILE - In this Aug. 20, 2014 file-pool photo, Attorney General Eric Holder speaks with Capt. Ron Johnson of the Missouri State Highway Patrol at Drake's Place Restaurant in Ferguson, Mo. As local authorities in Missouri near the end of their investigation into the Ferguson shooting, a separate, ongoing federal civil rights review of the entire police department holds the greater potential to refashion the agency and spur long-lasting change, experts say. The Justice Department, which is investigating the Aug. 9 shooting of 18-year-old Michael Brown along with a county grand jury, is more than two months into its probe of the Ferguson department’s practices. The civil rights inquiry, relying on data and interviews, is searching for any pattern of racial bias in how officers in the predominantly white department interact with the majority-black community.
