By exploring the current, post-9/11 operations of the NSA [National Security Agency, James] Bamford ... goes where congressional oversight committees and investigative journalists still struggle to go. [When] the Bush administration declared its ... global war on terror, Congress agreed to most of the White House's demands. According to Bamford, the NSA's expanded powers and resources enabled it to collect communications both inside and outside the United States. He quotes a former NSA employee as a witness to the agency's spying on the conversations of Americans who have no connection to terrorism. After suing the NSA for documents, [Bamford] obtained considerable evidence that telecommunication companies (with the notable exception of Qwest) knowingly violated U.S. law by cooperating with the NSA to tap fiber optic lines. In impressive detail, The Shadow Factory: The Ultra-Secret NSA from 9/11 to the Eavesdropping on America tells how private contractors, including some little-known entities with foreign owners, have done the sensitive work of storing and processing the voices and written data of Americans and non-Americans alike. In the book, he offers new revelations about the National Security Agency's counterterrorism tactics, including its controversial domestic surveillance programs. Bamford warns of worse to come: 'There is now the capacity to make tyranny total in America. Only law ensures that we never fall into that abyss -- the abyss from which there is no return.'"
