Group leaders say they want better community control over alleged police brutality and policing methods.
On the city's West Side, demonstrators chanted, "Fight back against police brutality," at the intersection of Madison and Pulaski.
One woman claims police used excessive force by shooting her 13-year old grandson in the back 13 times.
CHURCHES PLAN SUNDAY UNITY MARCH
Several Chicago churches are planning a unity march Sunday after the recent decisions not to indict the officers in the Garner and Michael Brown cases.
The group is scheduled meet up at 3860 West Ogden at 11 a.m. Sunday before walking east on Ogden to Central Park to block traffic on all sides.
There will be prayers and speeches on unity and justice. Organizers are expecting about 500 people.
