Wired correspondent James Bamford describes the $2 billion Utah Data Center that is being constructed for the National Security Agency. It’s expected to be up and running in 2013 and will house their database for all forms of communication—emails, cell phone calls, Internet searches, and even bookstore purchases.

The National Security Agency, which would prefer to keep a low profile, got a lot of publicity during the Bush Administration. In 2005 the nation learned that as a post-9/11 reflex, President Bush had authorized the NSA to wiretap the phone and email communications of U.S. citizens. A new NOVA documentary, “The Spy Factory,” details how the NSA could have prevented the 9/11 attacks and how it has subsequently violated the privacy of millions of Americans. Joining us to talk about the NSA is journalist James Bamford. He is the writer and co-producer of the NOVA documentary, which is based on his book, The Shadow Factory.

Don't forget to tune into Nova's documentary, The Spy Factory.

Find out how the National Security Agency evolved after 9/11, and how it might change again under the incoming Obama administration. James Bamford is author of The Shadow Factory.

If the NSA is listening to your phone calls and reading your emails, would you want to know about it?
