Advocacy groups and community leaders are calling for more investigations of the Chicago Police Department and authorities after the release of a video that shows a white police officer shooting a black teen.
The video was released hours after the officer was charged with first-degree murder.
The Urban League of Chicago called for a federal Department of Justice investigation, alleging a pattern of "discriminatory harassment" against black people.
The Rev. Jesse Jackson says officers involved should be fired or at least suspended. He also wants a special prosecutor on the case, saying Cook County State's Attorney Anita Alvarez took too long to bring a murder charge in the 2014 shooting.
