Friends and relatives of 15-year-old shooting victim Justin Thompson hold a candlelight vigil for him on Sept. 28, 2012 in Memphis, Tenn. The teen's shooting by an off-duty Memphis police officer is the latest incident being used by critics of the city's police department to push for reforms from the outside. This year, at least 23 Memphis officers and civilian personnel have been charged with crimes, from DUI and drug dealing to human sex trafficking. Going back to 2004, dozens of officers in Tennessee's largest city have been charged with corruption. (AP Photo/Adrian Sainz)
