Chicago Mayor Rahm Emanuel has invited ministers and community activists to City Hall to discuss the upcoming release of a police car dashcam video that shows a white officer fatally shooting a black teenager last year.
Seventeen-year-old Laquan McDonald was shot 16 times. Police have said he refused to drop a knife.
There is growing concern in the community about what could happen when people see the incident for themselves. A judge last week ordered the video released no later than Wednesday.
Two ministers invited to the meeting Monday afternoon say they think Emanuel is going to ask them to call for calm.
Ira Acree and Marshall Hatch say blacks in the city are upset about the shooting and the city's refusal for several months to release the video.
