I've got stacks of letters from gun owners who want me to know that they care passionately about their right to bear arms, don't want them infringed upon, and I appreciate every one of those letters. I've learned from them. But a lot of those letters, what they've also said is they're not just gun owners; they're also parents or police officers or veterans, and they agree that we can't stand by and keep letting these tragedies happen; that with our rights come some responsibilities and obligations to our communities and ourselves, and most of all to our children. We can't just think about "us" -- we've got to think about "we, the people."
