It comes at the end of weeks of nationwide protests against police brutality of unarmed black men and boys. On December 3, a grand jury decided not to indict an NYPD officer who killed Eric Garner in a chokehold. The incident was filmed, and Garner, who was unarmed and had asthma, can be heard screaming "I can't breathe." On November 24, in Ferguson, Missouri, a different grand jury failed to indict the police officer who shot and killed 18-year-old Michael Brown. On November 22, another 12-year-old, Tamir Rice, was killed by cops in Cleveland.
