Hundreds of protesters are blocking entrances to stores in Chicago's high-end shopping district on Black Friday to draw attention to the police shooting of a black teenager.
Some of the demonstrators linked arms to form human chains in front of main entrances to stores on both sides of Michigan Avenue for more than three blocks.
The largest is a peaceful group led by Rev. Jesse Jackson, who delivered a prayer from the steps of Chicago's historic Water Tower.
Rev. Jackson was in the middle of the crowd shouting, "What do we want? Justice. When do we want it? Now!''
