FILE – In this Monday, Oct. 13, 2014 file photo, Pastor Charles Burton lies on the driveway of the Ferguson, Mo., police station as he is outlined in chalk as a memorial to Michael Brown. Some witnesses said 18-year-old Brown had his hands up in surrender, others said he was making a charge. But there was no dispute he was unarmed and shot dead by a white police officer. In New York City, another unarmed black man, Eric Garner, was killed after a white officer put him in a chokehold during an arrest for unauthorized cigarette sales. After grand juries opted not to indict the officers, protests erupted across the country, punctuated by chants of “Hands up, don’t shoot” and “I can’t breathe.” (AP Photo/Charles Rex Arbogast, File)
