CHICAGO, IL - DECEMBER 13: Demonstrators march along the Magnificent Mile shopping district on Michigan Avenue to protest police abuse, December 13, 2014 in Chicago, Illinois. About 25 of the approximately 200 demonstrators were arrested during the protest which weaved its way through sidewalks packed with Christmas shoppers. The protests was one of many staged nationwide in response to grand juries' failure to indict police officers involved in the the deaths of Michal Brown in Ferguson, Missouri and Eric Garner in New York.
