Police officers around the country have been able to protect themselves against citizen complaints by wearing tiny body cameras, but a federal judge's plan to force some New York City officers to start wearing the devices has angered the mayor and police unions.
Mayor Michael Bloomberg criticized the cameras as unnecessary for the 35,000-officer New York Police Department, while police reform advocates have cautiously agreed to the idea in theory, with some caveats. People on both sides have raised privacy concerns in a city that already has thousands of public and private cameras.
