President Obama has said the US must do more to protect its children after the shootings in Newtown in the state of Connecticut.
He spoke at an inter-faith service in the town on Sunday.
If Obama attempts to tackle America's gun culture, he will meet a great deal of opposition.
Richard Feldman, President of the Independent Firearm Owners Association, told the Today programme: "The problem is whose hands the guns are in.
"This particular case, and all the other mass shootings, involved mentally deranged individuals. We have a failed mental health system now in this country.
"Having a ban isn't going to make the very people we would like to prevent from having them, having them. They're already owned by tens of millions of people."
