The ACLU of Pennsylvania and the law firm of Kairys, Rudovsky, Messing & Feinberg filed a federal class action on November 4, 2010, on behalf of eight African-American and Latino men who were stopped by Philadelphia police officers solely on the basis of their race or ethnicity. The suit alleges that thousands of people each year are illegally stopped, frisked, searched, and detained by the Philadelphia Police Department as part of its stop-and-frisk policy.
