President Obama took to the White House blog this morning to address the deadly Aurora, Colorado massacre Friday morning at a midnight screening of The Dark Knight Rises, in which 12 people have already been confirmed dead.

"Even as we come together to learn how this happened, and who's responsible, we may never understand what leaves anyone to terrorize their fellow human beings. Such evil is senseless, beyond reason," President Obama says. "If there's anything to take away from this tragedy, it's a reminder that life is fragile – our time here is limited, and it is precious. And what matters in the end, are not the small and trivial things which so often consume our lives -- it's how we choose to treat one another, and love one another."
