Chicago mayor Rahm Emanuel is facing mounting criticism from activists and allies of the black community who say he should be held accountable for delaying justice in the case of Laquan McDonald, a teenager who died 13 months ago after being shot 16 times by a Chicago police officer. A court order forced Chicago city officials to release squad car video of the gruesome death, which they did on Tuesday, hours after the Cook County State's Attorney's office charged Officer Jason Van Dyke with first-degree murder in the teen's killing.
