President Barack Obama
“We’re not doing enough and we will have to change. We can’t tolerate this anymore. These tragedies must end, and to end them, we must change. We will be told that the causes of such violence are complex, and it is true. No single law, no set of laws can eliminate evil from the world or prevent every senseless act of violence in our society. But that can’t be an excuse for inaction. Surely we can do better than this.”
