It's called the "Wall of Shame."
Tucked away in the hall of an office building outside the nation's capital in Bethesda, Md., the wall features the portraits of double agents, traitors, leakers and saboteurs.
It's not a display most Americans will ever see. In fact, it requires a top-secret security clearance to ride the elevator up to the floor it's on.
The wall include photos and dossiers of Robert Hannsen, Aldrich Ames, Jonathan Pollard — among others — who all pleaded guilty to revealing America's secrets.
