CHICAGO, IL - DECEMBER 06: Demonstrators led by Rev. Jesse Jackson march down State Street to protest the death of Laquan McDonald and the alleged cover-up that followed on December 6, 2015 in Chicago, Illinois. Chicago Police officer Jason Van Dyke shot and killed 17-year-old McDonald on October 20, 2014, hitting him with 16 bullets. Van Dyke was charged with murder more than a year after the shooting after a judge ordered the release to the public of a video which showed McDonald backing away from Van Dyke while being shot.
