Costner: America is 'something to protect'

"The one thing I love about America is, you can go in that booth and you can still close the curtain on what it is you think, and do what you feel is right," says Kevin Costner. "And there's times when you can feel like your voice needs to be heard, there's other times when you need to listen.....we have something to protect, something to push forward, and the only way we get there is to lose our ego, and to fall back and have a higher understanding of what public service means."
