In his first extensive public remarks since the mass shooting at a Connecticut school last Friday, the head of National Rifle Association called Friday for all schools to have armed police officers in an effort to curb violent outbreaks akin to the Connecticut shooting.

"The only thing that stops a bad guy with a gun is a good guy with a gun," NRA Executive Vice President Wayne LaPierre said at a news conference in Washington. LaPierre also called on Congress to act immediately "to appropriate whatever is necessary to put armed police officers in every school in this nation."
