There is plenty of news still swirling around the issues of police shootings, allegations of abuse, and how they are investigated, including mayoral apologies and the launching of a federal probe. Even as the fallout from the shooting death of Laquan McDonald by Officer Jason Van Dyke continues, questions mount around other incidents of alleged police abuse in Chicago. Cook County Circuit Judge Police Commander Glenn Evans was acquitted Monday on charges of aggravated battery over allegations he shoved his service revolver down the throat of a drug suspect. Many of the cases under scrutiny now involve video. The Sun-Times reviewed three recent cases in which the city paid out millions. In each, the videos appeared to contradict the police accounts; in none of them, unlike McDonald’s shooting, was the officer charged.
