Advocacy group secretly tapes Supreme Court session

WASHINGTON - Despite metal detectors, security, and a long tradition of "no cameras allowed," a session of the U.S. Supreme Court was videotaped by an advocacy group.

The recording of justices in session is an apparent first.

There are only two known photographs of the court taken while the justices were in session.

They were taken when cameras were smuggled into the court in the 1930s.

But a clip uploaded to YouTube, a group apparently managed to sneak cameras past security, using them to record what's believed to be the first video of the Supreme Court in session.

"I certainly never expected anyone would be able to smuggle a camera in there."

Author and legal analyst Jeffrey Toobin explains SCOTUS security isn't exactly lax.

"I am baffled, because I've been in the court many times, and even the news media has to walk through metal detectors. We're not allowed to bring electronics in. Everybody passes through those metal detectors."

This wasn't just a prank. This video was recorded by an advocacy group which pushes for campaign finance reform. One man stood to voice disapproval of the high court's 2010 decision to loosen restrictions on corporate campaign spending.

"I rise on behalf of the vast majority of the American people who believe that money is not speech, corporations are not people, and our democracy should not be for sale to the highest bidder," he said.

Security was on him in seconds. He now faces federal charges. As to the how the group smuggled the cameras into the room, the Supreme Court said it is reviewing the video and its screening procedures.
