The NRA's news conference Friday morning had one unexpected visitor: a protestor with a big pink sign.

NRA Executive Vice President Wayne LaPierre was proposing his organization's solution to recent incidences of gun violence in Connecticut, Oregon, Wisconsin and Colorado: put an armed police officer in every school by the end of the year. While he was speaking, a man stood up with a sign reading "NRA killing our kids" directly in front of LaPierre's podium.

He was quickly forced out of the room, while screaming, "we should not arm teachers ... we've got to stop the violence ... we've got to stop the killing in our schools, stop the killing in our streets, the NRA is killing our children."

The protestor was from Code Pink, a self-described "women-initiated grassroots peace and social justice movement."
