WASHINGTON, DC - DECEMBER 04:  A man carries a sign with some of Eric Garner's last words, "I can't breath," in protest against  recent decisions by grand juries in the Michael Brown and Eric Garner cases, December 4, 2014 in Washington,DC. On Wednesday, a grand jury declined to bring charges against a white New York City Police Officer in the chokehold death of Eric Gardner, sparking further unrest in the wake of a grand jury's decision not to indict former Ferguson, Missouri Police Officer Darren Wilson in the shooting death of Michael Brown.
