CHICAGO (AP) -- The Chicago Police Department will allow independent evaluations of its stop-and-frisk procedures that critics say target blacks, under an agreement with the American Civil Liberties Union announced Friday, as police across the United States face scrutiny about how they treat minorities.
An ACLU report has identified more than 250,000 Chicago stop-and-frisk encounters in which there were no arrests from May through August 2014. African-Americans accounted for nearly three-quarters of those stopped, even though they make up about a third of the city's population.
Under the agreement, a former U.S. magistrate judge will provide public reports twice a year on Chicago police investigatory stops and pat downs, looking at whether the city is meeting its legal requirements. It goes into effect immediately.
The Chicago Police Department faces a federal lawsuit filed in April and seeking class-action status. In that lawsuit, six African-American Chicago residents claim the street stops have led to constitutional abuses, including unlawful searches and seizures as well as excessive force.
The city and department have agreed to collect additional data about investigatory stops. That includes officers' names and badge numbers, the race, ethnicity and gender of the person stopped, the reason for the stop, the location, date and time of the stop and other details.
That information will be given to the ACLU and the judge, who will oversee the agreement's implementation.
Chicago Police Superintendent Garry McCarthy has been a proponent of stop-and-frisk, and he worked at two police departments that came under criticism for their use of the tactic. The New York City Police Department has revamped its stop-and-frisk policy after a judge ruled that the tactic sometimes discriminated against minorities.
In Newark, the police department was placed under a federal monitor after the U.S. Department of Justice found that during a period when McCarthy ran that department, blacks accounted for 85 percent of the stops in a city where blacks make up 54 percent of the population.
