The U.S. Capitol building in Washington By Joshua Kaplan and Joaquin Sapien, ProPublica When Kim Dine took over as the new chief of the U.S. Capitol Police in 2012, he knew he had a serious problem. Since 2001, hundreds of Black officers had sued the department for racial discrimination. They alleged that white officers called Black colleagues slurs like the N-word and that one officer found a hangman’s noose on his locker. White officers were called “huk lovers” or “FOGs” short for “friends of gangsters” if they were friendly with their Black colleagues. Black officers faced “unprovoked traffic stops” from fellow Capitol Police officers. One Black officer claimed he heard a colleague say, “Obama monkey, go back to Africa.”
