This is an excerpt from comments President Obama made Saturday at a memorial service for victims of the Newtown, Conn., school shooting.

Someone once described the joy and anxiety of parenthood as the equivalent of having your heart outside of your body all the time, walking around. With their very first cry, this most precious, vital part of ourselves — our child — is suddenly exposed to the world, to possible mishap or malice. And every parent knows there is nothing we will not do to shield our children from harm. And yet, we also know that with that child’s very first step, and each step after that, they are separating from us; that we won’t — that we can’t always be there for them. They’ll suffer sickness and setbacks and broken hearts and disappointments. And we learn that our most important job is to give them what they need to become self-reliant and capable and resilient, ready to face the world without fear.
And we know we can’t do this by ourselves. It comes as a shock at a certain point where you realize, no matter how much you love these kids, you can’t do it by yourself. That this job of keeping our children safe, and teaching them well, is something we can only do together, with the help of friends and neighbors, the help of a community, and the help of a nation. And in that way, we come to realize that we bear a responsibility for every child because we’re counting on everybody else to help look after ours; that we’re all parents; that they’re all our children.
This is our first task — caring for our children. It’s our first job. If we don’t get that right, we don’t get anything right. That’s how, as a society, we will be judged.
And by that measure, can we truly say, as a nation, that we are meeting our obligations? Can we honestly say that we’re doing enough to keep our children — all of them — safe from harm? … I’ve been reflecting on this the last few days, and if we’re honest with ourselves, the answer is no. We’re not doing enough. And we will have to change.
Since I’ve been president, this is the fourth time we have come together to comfort a grieving community torn apart by a mass shooting. The fourth time we’ve hugged survivors. The fourth time we’ve consoled the families of victims. And in between, there have been an endless series of deadly shootings across the country, almost daily reports of victims, many of them children, in small towns and big cities all across America — victims whose — much of the time, their only fault was being in the wrong place at the wrong time.
We can’t tolerate this anymore. These tragedies must end. And to end them, we must change. We will be told that the causes of such violence are complex, and that is true. No single law — no set of laws can eliminate evil from the world, or prevent every senseless act of violence in our society.
But that can’t be an excuse for inaction. Surely, we can do better than this. If there is even one step we can take to save another child, or another parent, or another town, from the grief that has visited Tucson, and Aurora, and Oak Creek, and Newtown, and communities from Columbine to Blacksburg before that — then surely we have an obligation to try.
In the coming weeks, I will use whatever power this office holds to engage my fellow citizens — from law enforcement to mental health professionals to parents and educators — in an effort aimed at preventing more tragedies like this. Because what choice do we have? We can’t accept events like this as routine. Are we really prepared to say that we’re powerless in the face of such carnage, that the politics are too hard? Are we prepared to say that such violence visited on our children year after year after year is somehow the price of our freedom?
