A Cook County judge yesterday ordered Chicago to release video from a police dash-cam that shows a white officer shooting 17-year-old LaQuan McDonald 16 times. Police say McDonald was high on the drug PCP, was wielding a knife and lunged at the officer. There was a witness who said McDonald never lunged at the cop. The video might answer questions about the shooting, but it could also ratchet up simmering tensions in Chicago between police and African American residents — tensions that have reached a boiling point in other cities around the country. We hear from listeners about whether they’ll watch the video and why. WBEZ’s senior editor for news, Rob Wildeboer, who spent years covering the Chicago Police, tells us more about police procedures in incidents like this. (Flickr/David D’Agostino)
