One of History's 'Most Important Documents' Goes on Sale

The Magna Carta—signed by the King of England 700 years ago—established the rules of law that are basic to the United States and other governments all over the world.  There's only one original copy in private hands, and next week it's going on sale. We hear what it will cost and how important it is to debates about civil rights, national security and Guantánamo Bay. Also, a possible compromise out of the UN Climate Change Conference in Bali, and "The Steroid Era" of Major League Baseball, including reaction from former team owner George W. Bush.
