New York City Mayor Michael Bloomberg gestures while speaking to the media about a judge's ruling on 'stop and frisk' at City Hall in New York August 12, 2013. Bloomberg said he would appeal a federal judge's ruling on Monday that the police department's 'stop and frisk' crime-fighting tactics violate constitutional rights, arguing that the practice drove down the city's crime rate.
