It comes as a shock at a certain point where you realize, no matter how much you love these kids, you can’t do it by yourself. That this job of keeping our children safe, and teaching them well, is something we can only do together, with the help of friends and neighbors, the help of a community, and the help of a nation. And in that way, we come to realize that we bear a responsibility for every child because we’re counting on everybody else to help look after ours; that we’re all parents; that they’re all our children.
Obama added:
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 that 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.
