Following the attacks of September 11, 2001, the National Security Agency stepped up its efforts to collect intelligence domestically by filtering millions of phone conversations and e-mail messages. In his new book, The Shadow Factory: The Ultra-Secret NSA From 9/11 To The Eavesdropping On America, journalist James Bamford reveals that the ultra-secret agency has half a million people on its watch lists.
Bamford has been writing about the inner workings of the NSA since his first book, The Shadow Factory: A Report On America's Most Secret Agency, was published in 1982. He is also the author of Body Of Secrets: Anatomy Of The Ultra-Secret National Security Agency.
