In Chicago, the trial of Jason Van Dyke, the police officer who killed Laquan McDonald, is underway. On the opening day of the trial, the jury was shown the now-viral dash cam video showing Van Dyke shooting the unarmed African-American teenager 16 times as he walks away from him. Van Dyke faces two counts of first-degree murder. He is the first police officer in Chicago to stand trial for killing someone on duty in 50 years. Last year, three Chicago police officers were indicted on felony charges for conspiring to cover up the facts of McDonald’s shooting. Chicago Mayor Rahm Emanuel has also been sharply criticized for his response to the killing, namely in the delayed release of the dash cam evidence.
