Meanwhile, in Chicago, white police officer Jason Van Dyke has been formally indicted on six counts of first-degree murder for the fatal shooting of 17-year-old Laquan McDonald more than one year ago. Dash cam video, only recently released by court order, shows the teenager posing no threat and walking away from the officers at a distance as Officer Van Dyke jumps out of his police car and opens fire, striking McDonald 16 times. The case has sparked massive protests across Chicago, the ouster of former Chicago Police Chief Garry McCarthy, and increasing calls for Chicago Mayor Rahm Emanuel’s resignation. On Wednesday, as Mayor Emanuel was visiting the boys’ charter school Urban Prep Charter Academy in the South Side neighborhood of Englewood, students began chanting “16 Shots”—the slogan many protesters have been using in calling for Emanuel’s resignation.

Students: “Sixteen shots! Sixteen shots! Sixteen shots!”

Mayor Emanuel abruptly left after the assembly.
