Pittsburgh Police Chief Cameron McLay set off a battle with police unions when he posed with a sign that reads, ‘I resolve to challenge racism @ work #EndWhiteSilence.’ Some think this means policemen are racists. McLay says the sign is not against anyone, and that he was just showing support to anti-racism campaigners. After several black men were shot by police in 2014, McLay wants to show that no racism will be accepted within the police force.
