CHICAGO (AP) - Organizers estimate that roughly 50 to 100 protesters marched and rallied on Chicago's South Side after authorities decided not to bring charges against a Chicago officer who fatally shot a 25-year-old man in 2014.
The protesters are from groups including Action Now, Black Youth Project 100 and Black Lives Matter.
They gathered Monday near the site where Ronald Johnson III was fatally shot by a Chicago police officer. Some chanted for Cook County State's Attorney Anita Alvarez and Mayor Rahm Emanuel to step down.
Participants included Johnson's mother, Dorothy Holmes.
The protest capped a flurry of activity Monday that included the U.S. Department of Justice announcing a wide-ranging probe of police department practices and Alvarez deciding not to bring charges in the Johnson case.
Another protest is set for Wednesday morning.
