#ENOUGH: Striking instant camera photos memorialize victims of Chicago gun violence

Last year, photographer Jim Young visited murder scenes and memorials in Chicago and documented what he saw with an instant camera. Last year, there were 650 murders in the area with 90 percent of them involving guns. Enough. "Though most of the [memorials] are gone," Young says, "their photographs will be forever, and I hope memories [of the victims] will be, too." See the series at FOTO: "Behind the Bullets"
