The street Crimes Unit of the New York City Police Department will have to defend a challenge to its “stop-and-frisk” policy brought by black and Latino men following a decision yesterday by Southern District Judge Shira A. Scheindlin.

The street crimes unit, already under scrutiny by the U.S. Department of Justice and Attorney General Eliot Spitzer for stop-and-frisks, lost its bid to have a class action civil rights suit dismissed in National Congress for Puerto Rican Rights v. The City of New York, 99 Civ. 1695.
