In August 2014, Darren Wilson, a white policeman in Ferguson, Missouri shot and killed Michael Brown, an 18-year-old unarmed black man who had robbed a nearby convenience store fifteen minutes earlier. While a grand jury investigation found that Wilson had acted in self-defense after Brown attacked him on two separate occasions, locals hostile to the police claimed that Brown had been gunned down while surrendering. Racial tensions in Ferguson between the mainly black population and mainly white police force led to both peaceful protests and riots, and several buildings were looted and set on fire. In response, the Ferguson Police Department deployed military-grade riot gear and riot control weaponry to disperse crowds and maintain order. Further protests erupted after the death of Eric Garner, a 43-year-old black resident of Staten Island, New York who died after being put in a nineteen-second long chokehold by NYPD officer Daniel Pantaleo while resisting arrest. Garner was being investigated by the NYPD under suspicion of illegally selling cigarettes. Pantaleo's acquittal by a grand jury in December led to nationwide protests by a movement which came to call itself Black Lives Matter.
