New York Times: Spy Agency Data After Sept. 11 Led F.B.I. to Dead Ends: “President Bush has characterized the eavesdropping program, which focused on the international communications of some Americans and others in the United States, as a “vital tool” against terrorism; Vice President Dick Cheney has said it has saved “thousands of lives.” But the results of the program looked very different to some officials charged with tracking terrorism in the United States. More than a dozen current and former law enforcement and counterterrorism officials, including some in the small circle who knew of the secret eavesdropping program and how it played out at the F.B.I., said the torrent of tips led them to few potential terrorists inside the country they did not know of from other sources and diverted agents from counterterrorism work they viewed as more productive.”
