A mournful President Obama said during his visit to Newtown, Conn., on Sunday that the nation is failing to keep its children safe, pledging that change must come after an elementary-school massacre left 20 children dead.
"What choice do we have?" Obama said. "Are we really prepared to say that we're powerless in the face of such carnage, that the politics are too hard?"
In a vigil for the fallen, in a moment of grief that spread around the world, Obama conceded that none of his words would match the sorrow. But he declared to the community of Newtown: "You are not alone."
