NYPD crowd control officers keep watch on a march of demonstrators as they protest against the shooting of Kimani "Kiki" Gray on Thursday, March 14, 2013 in the East Flatbush neighborhood of Brooklyn, N.Y. The 16-year-old was shot to death on a Brooklyn street last Saturday night by plainclothes police officers who claim the youth pointed a .38-caliber revolver at them, while the family says Gray was unarmed.
