Civil rights activists are protesting against the NYPD's tactic of stopping and frisking people on the street. The NYPD says the practice is a crime-fighting tool, but opponents say it primarily targets African-Americans and Latinos. They also say most stops fail to lead to an actual arrest or summons. The New York Civil Liberties Union says 9 out of 10 people stopped last year were found to be innocent.Rally puts spotlight on police-search policyProtest held against NYPD's 'stop-and-frisk' policy
