WASHINGTON (AP) -- The nation's largest gun-rights lobby is calling for armed police officers to be posted in every American school to stop the next killer "waiting in the wings."

The National Rifle Association broke its silence Friday on last week's shooting rampage at a Connecticut elementary school that left 26 children and staff dead.

The group's top lobbyist, Wayne LaPierre, said at a Washington news conference that, quote, "The only thing that stops a bad guy with a gun is a good guy with a gun."

LaPierre called for establishment of a program to place an armed police officer in every school in America. He also blamed the American media for allowing violent culture to come into children's homes.

The NRA announced a new program, the NRA Education And Training Emergency Response Program, as part of a new website, The National School Shield, to assist in efforts to launch armed guards in schools.
