A group of black police officers is suing the Philadelphia Police Department over an Internet discussion board on which officers have allegedly posted hundreds of racist comments.
The Guardian Civic League filed the federal civil rights lawsuit Thursday.
The league, along with the National Association for the Advancement of Colored People, wants the department to have the site shut down. The suit also seeks to have those behind it disciplined.
The 10-year-old Web forum, Domelights.com, is not run by the department. But the suit says officers often make postings from department computers.
The lawsuit cites racially derogatory commentary on the site, including one posting that says: "Guns don't kill people ... Dangerous minorities do."
Messages left for a police department spokesman and the Fraternal Order of Police were not immediately returned.
