FILE - This combination of undated photos provided by the Brown family and the Garner family via the National Action Network shows Michael Brown, left, the black 18-year-old who was fatally shot by a white police officer in Ferguson, Mo. in August 2014, and Eric Garner, who died after a white police officer had him in a chokehold in the Staten Island borough of New York in July 2014. The cases of Brown and Garner involve an unarmed black man killed by a white police officer in a confrontation over a relatively minor crime. But there are sharp differences, too, in the circumstances of the Aug. 9 and July 17 killings. (AP Photo/Brown Family, Garner Family via National Action Network)
