A federal judge in New York has given a green light to a lawsuit over police frisks. The class-action suit alleges New York City police officers subject people in high-crime areas to frisks based on their race. The suit was filed on behalf of six African American and Latino men. It seeks to eliminate frisks that occur without probable cause and also seeks unspecified money damages. It was filed after four police officers were accused of fatally shooting an unarmed East African immigrant, Amadou Diallo, 19 times outside his home in February. The federal judge says the police department may have a pattern of unconstitutional stops and frisks.
