Here’s a follow-up on a video WBEZ has been reporting about. That video, shot March 19, shows a young man in the backseat of a Chicago police SUV. A back door is open and he’s getting taunted by onlookers who flash gang signs — while two officers seem to stand by. The police department has assigned those officers to desk duty and started an internal investigation. WBEZ is not naming them at this time. Some Northwest Side residents, meanwhile, are petitioning the department to put those two cops back on their beat. WBEZ’s Chip Mitchell connected with Eric Hudson, a resident behind that effort. They spoke near Hudson’s home, just blocks from where the video was shot. Hudson has worked with the two officers to root out gangs from his own corner. As he explains in this six-minute interview (below), he has also worked to hold police accountable for abuses.
