America, this is our moment. This is our time. Our time to turn the page on the policies of the past. Our time to bring new energy and new ideas to t… - Barack Obama

Ayn Rand is one of those things that a lot of us, when we were 17 or 18 and feeling misunderstood, we'd pick up. Then, as we get older, we realize that a world in which we're only thinking about ourselves and not thinking about anybody else, in which we're considering the entire project of developing ourselves as more important than our relationships to other people and making sure that everybody else has opportunity – that that's a pretty narrow vision.

No one -- no one -- has given more for our freedom and our security than our Gold Star families. ... They represent the very best of our country. They continue to inspire us every day, every moment. They serve as a powerful reminder of the true strength of America. We have to do everything we can for those families, and honor them, and be humbled by them.

Someone once wrote, “A bullet need happen only once, but for peace to work we need to be reminded of its existence again and again and again.” My fellow Americans, only we can prove, through words and through deeds, that we will not be divided. And we’re going to have to keep on doing it “again and again and again.” That’s how this country gets united. That’s how we bring people of good will together. Only we can prove that we have the grace and the character and the common humanity to end this kind of senseless violence, to reduce fear and mistrust within the American family, to set an example for our children. That’s who we are, and that’s who we always have the capacity to be. And that’s the best way for us to honor the sacrifice of the brave police officers who were taken from us this morning.
