CNN's Miles O'Brien spoke Thursday with Lesley Cauley, the USA Today reporter who broke the story.
http://www.cnn.com/2006/POLITICS/05/11/cauley/index.htmlO'BRIEN: All right, the amount of data here is truly staggering, and I'm sure that the NSA has some of the finest supercomputers on the planet. But what are they able to do when they put all those phone numbers and all of those records into the computer? What can they possibly learn?
CAULEY: Well, only the NSA knows that for sure and they are not saying. But certainly with this aggregated mass of data, they can slice and dice this a multitude of ways and you cross-check it with other databases, other information, they would have access to, which is considerable, and, again, secret. There's no telling. But that -- that is a question.
O'BRIEN: Do you know if there have been specific investigations or arrests, for that matter, that have been generated by this data?
CAULEY: I do not know for sure. I have not been able to determine that.
O'BRIEN: All right. And as far as we know, how long has this been going on?
CAULEY: Since at least -- since at least 2001, with the 9/11 attacks. Possibly the groundwork was laid prior to that. But certainly since 2001.
