President Obama spoke Sunday to a grieving nation following his visit with survivors of the Colorado theatre massacre and family members of the 12 dead, promising that their strength and courage will long outlive the infamy of the shooter.

“The attention of the perpetrator will fade away … and what will be remembered are the good people,” the president said in a speech at the University of Colorado Hospital.

The brief speech was both spiritual and presidential, with Obama quoting scripture, thanking doctors and first-responders, vowing the shooter would feel the “full force of the justice system” and calling for the country’s leaders to “do something about this senseless violence.”
