If you don't at least get a lump in your throat at the raw pain and grief of these parents of the victims of the Sandy Hook shootings, you don't have a heart.

But good for CBS News and 60 Minutes for putting their unflinching faces on air to confront those who will ignore the horror of Sandy Hook and still argue against any kind of sensible gun safety legislation.

David Wheeler: I would like every parent in this country -- that's 150 million people. I would like them to look in the mirror. And that's not a figure of speech, Scott. I mean, literally find a mirror in your house and look in it and look in your eyes and say, "This will never happen to me. This will never happen in my school. This will never happen in my community." And see if you actually believe that. And if there is a shadow, the slightest shadow of doubt about what you've said, think about what you can do to change that in your house, in your community, in your school, in your country, because we have an obligation to our children to do this for them. It's gonna happen again. It is going to happen again. And every time, you know, it's somebody else's school, it's somebody else's town. It's somebody else's community until one day you wake up and it's not.

As a parent, I know it will kill me to go through the unimaginable horror of what these parents have gone through. Their bravery, their unity and their commitment to make sure that their loss means something will change is simply amazing. Imagine yourself as Dylan Hochley's or Ana Greene's parents:

They're not asking for guns to be eliminated. They're asking for universal gun checks (an incredibly popular item) and limiting clips. Shame on any of us cowed by the NRA to not do even these little things.

Do it for those 26 Newtown residents and their grieving families.
