City attorneys have asked a US appeals court to vacate a federal judge's decision ordering the New York Police Department to curtail its stop-and-frisk tactics, after the same court removed the judge from the case but left her ruling intact. The "public perception of the NYPD has been clouded" by US District Judge Shira Scheindlin's August ruling against the department, city attorneys wrote in the motion filed late Saturday. Scheindlin's order "lends credence to the notion that the NYPD unfairly targets minorities for stops and frisks, undermining its ability to carry out its mission effectively," New York City Corporation Counsel Michael Cardoza wrote.
