Chicago Police Superintendent Speaks at Press Conference Before Laquan McDonald Shooting Video Released

WGN- Police Superintendent Garry McCarthy speaks at a press conference on Nov. 24, 2015 before releasing the police dashcam video that captured the police shooting of Laquan McDonald. The October 2014 video shows 17-year-old Laquan McDonald shot repeatedly as he walked down the middle of a Southwest Side street, part of the evidence to support allegations that Officer Jason Van Dyke fired 16 shots into the teen's body in 14 seconds. Cook County State's Attorney Anita Alvarez charged Van Dyke with first-degree murder the same day of the dashcam video release, saying she made the announcement earlier than planned out of concern for "public safety."
