VICE News is closely watching policing in America. Check out the Officer Involved blog here.Pittsburgh's top cop has ordered an investigation of himself after police union officials accused the chief of violating the bureau's social media policy after he posted a controversial tweet condemning racism.Chief Cameron McLay tweeted a picture of himself holding a sign saying: "I resolve to challenge racism @ work," accompanied by the hashtag #EndWhiteSilence, on New Year's Eve.The tweet referred to recent protests that have swept through the nation in the wake of several police killings of unarmed black men. It was applauded by Pittsburgh Mayor Bill Peduto, who posted the photo to his Facebook page, but not everyone was impressed.Howard McQuillan, the president of the Fraternal Order of Police Lodge No. 1, accused McLay of breaching a police department policy on use of social media and of casting police in a bad light by broadly labeling them all as racists.In response, McLay suspended his Twitter account and called for an investigation of his actions, saying, "If I'm going to talk about integrity of processes, it starts with me.""I have very, very little concern that I've violated policies," he added, according to the Guardian.
