Hank Partin Roanoke Police Chief Sam Roman Mike Crawley Chief Howard Hall flipped through the notes heâs made from exit interviews over the past year: There was an officer who left to go into nursing, another who went to an insurance company, one became a welder, two planned to make the move to the roofing business. In total, Roanoke County saw 28 of its police officers leave during 2020, about one-fifth of its department. That is both abnormal and normal all at once â abnormal because itâs twice as high as the turnover the agency would expect in a typical year. Normal because it tracks with a surge in police departures unfolding nationwide.
