CHICAGO -- Cook County State's Attorney Anita Alvarez will make an announcement Tuesday about whether or not a white Chicago police officer will be charged in the shooting of a black teenager, a source tells WGN.
Last year, 17-year-old Laquan McDonald was shot 16 times. Police have said he refused to drop a knife.
A Cook County judge ordered last week that dashcam video of the shooting be released no later than Wednesday.
Chicago Mayor Rahm Emanuel invited ministers and community activists to City Hall Monday to discuss the upcoming release of the video. There is growing concern in the community about what could happen when people see the incident for themselves.
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.
Members of several black youth organizations say they refused an invitation to sit down with Emanuel, instead holding their own news conference at the second district police precinct. They say the mayor refused to meet with them recently to talk about the month long Dyett High School hunger strike, as well as the multi-year battle for a level-one trauma center on the South Side.
They say they feel the city tried to hide this video, and feel they don't owe the mayor anything.
