Corruption in Chicago investigations of Pd use of force reviews

In Chicago, one of America's most corrupt cities, an "investigator with seven years on Chicago’s Independent Police Review Authority — who previously served 23 years as a cop, detective and commander — was fired because he refused to reverse his conclusions into several police shootings of civilians, reports WBEZ after a review of agency records." It's  no wonder that many supposed remedies do not work.  You can't let the foxes and their sympathizers control the hen house.
