President Barack Obama said it is clear that change in gun control laws would not come from Washington, but would have to come from people demanding action.
Obama spoke at a memorial service on Sunday honoring memories of the those killed at last week's Navy Yard shooting. The incident sparked debate once again about gun control and mental health.
Obama noted that shootings in the United Kingdom and Australia have lead to law reform in those countries.
He also said that Americans are more susceptible to mass shootings because we haven't taken what he calls "common sense action" regarding gun control.
"If we can prevent even one tragedy like this, save even one life, spare other families what these families are going through, surely we got an obligation to try," the president said.
But National Rifle Association Vice President Wayne LaPierre said the problem is that guns are in the wrong hands.
He said the Navy Yard tragedy should never have happened and the breakdown of the mental health system in the nation factors into the problem.
"This is a tragedy that should not have happened, a memorial service that should not be taking place, and victims that should not be victims," La Pierre told NBC's "Meet the Press."
"The problem is there weren't enough good guys with guns," he said.
As the investigation continues, the FBI is uncovering more evidence of the shooter's unstable mental health.
Adding to the controversy over gun control, Starbucks has asked their customers to not bring guns into their establishments.
"We are respectfully asking our customers who are carrying a gun not to bring them inside Starbucks stores," CEO Howard Schultz said. "We are not pro-gun or anti-gun. But we do believe that guns and weapons should not be part of the Starbucks experience."
Schultz said the request from Starbucks is not a policy and will not be enforced. Still, customers have shown mixed reactions to the request.
