Don't get cynical. Don't ever think you can't make a difference.

The number of Americans killed since 9/11 by terrorism, it's less than 100. If you look at the number that have been killed by gun violence, it's in the tens of thousands. And for us not to be able to resolve that issue has been something that is distressing.
