The release of the disturbing video on orders of a Cook County judge has led to a torrent of protest and criticism over how Mayor Rahm Emanuel and the Police Department handled the investigation into the fatal shooting of the 17-year-old. After the video's release and days of protests, Emanuel fired police Superintendent Garry McCarthy and the head of the city's police oversight agency resigned just before the U.S. Justice Department announced a wide-ranging civil rights probe of the Police Department.
