More on Domestic Surveillance

Thanks to the holidays I'm a little late with this. But this article on the Dec. 24th NY Times confirms some earlier suspicions about the exact extent of the NSA domestic surveillance program:

The National Security Agency has traced and analyzed large volumes of telephone and Internet communications flowing into and out of the United States as part of the eavesdropping program that President Bush approved after the Sept. 11, 2001, attacks to hunt for evidence of terrorist activity, according to current and former government officials.

As part of the program approved by President Bush for domestic surveillance without warrants, the N.S.A. has gained the cooperation of American telecommunications companies to obtain backdoor access to streams of domestic and international communications, the officials said.

Since the disclosure last week of the N.S.A.'s domestic surveillance program, President Bush and his senior aides have stressed that his executive order allowing eavesdropping without warrants was limited to the monitoring of international phone and e-mail communications involving people with known links to Al Qaeda.

What has not been publicly acknowledged is that N.S.A. technicians, besides actually eavesdropping on specific conversations, have combed through large volumes of phone and Internet traffic in search of patterns that might point to terrorism suspects. Some officials describe the program as a large data-mining operation.

Officials in the government and the telecommunications industry who have knowledge of parts of the program say the N.S.A. has sought to analyze communications patterns to glean clues from details like who is calling whom, how long a phone call lasts and what time of day it is made, and the origins and destinations of phone calls and e-mail messages. Calls to and from Afghanistan, for instance, are known to have been of particular interest to the N.S.A. since the Sept. 11 attacks, the officials said.

This so-called "pattern analysis" on calls within the United States would, in many circumstances, require a court warrant if the government wanted to trace who calls whom.

It would seem then that in addition to eavesdropping on specific communications, the NSA has been looking at patterns in communications traffic. This is of course a far more extensive operation then it would appear Bush was admitting to when the news of the program was first revealed. I suppose whether you think Bush was lying by ommission in his radio address by failing to disclose this program depends on what your definition of "eavesdrop" is. At the same time though, you can be assured that we don't know all there is to know about this program.
