From the New York Times:
Blacks and Latinos were nine times as likely as whites to be stopped by the police in New York City in 2009, but no more likely to actually be arrested.
The more than 575,000 stops of people in the city — a record number of what are known in police parlance as “stop and frisks” — yielded 762 guns.
Of the reasons listed by the police for conducting the stops, one of those least commonly cited was the claim that the person fit the description of a suspect. The most common reason listed by the police was a category known as “furtive movements.”
Under Commissioner Raymond W. Kelly, the New York Police Department’s use of such street stops has more than quintupled, fueling both an intense debate about the effectiveness and propriety of the tactic and litigation aimed at forcing the department to reveal more information about the encounters.
