Chicago creates police task force after officer charged with murder

Chicago Mayor Rahm Emanuel on Tuesday announced the creation of a police accountability task force following days of unrest over the alleged murder of a black teenager by a white policeman. The announcement came a week after the officer, Jason Van Dyke, was charged with first-degree murder in the killing of Laquan McDonald, who was shot 16 times. "The shooting of Laquan McDonald requires more than just words," Emanuel said in a statement.
