“When incidents like this occur, there’s a big chunk of our citizenry that feels as if, because of the color of their skin, they are not being treated the same, and that hurts, and that should trouble all of us,” Obama said. “This is not just a black issue, not just a Hispanic issue. This is an American issue that we all should care about.”
