Chicago's top cop fired after black teen's shooting

Chicago's mayor said Tuesday he had fired the city's police chief after a graphic video of an officer shooting a black teenager 16 times sparked a week of protest. "The public trust in the leadership of the department has been shaken and eroded," Mayor Rahm Emanuel told reporters. Tensions flared after officials released a dashcam video last Tuesday showing police officer Jason Van Dyke kill Laquan McDonald by shooting him 16 times as the teenager walked away in October 2014.
