PHILADELPHIA, PA - DECEMBER 3:  Dancers perform during a Christmas Tree lighting ceremony at City Hall, in Philadelphia, Pennsylvania, while demonstrators gathered there to protest the Eric Garner grand jury decision on December 3, 2014. Organizers called for the demonstration after a grand jury in the Staten Island borough of New York City declined to indict the police officer who used a chokehold on Garner, resulting in his death.
