Former NSA Analyst Excoriates Data-Mining Program

Ira Winkler, in Computerworld, puts forth three strong arguments: The NSA program invades privacy, it's illegal on its face, and by its very nature generates thousands of "leads" with such a low signal-to-noise ratio that critical investigative resources are wasted:

This scattershot attempt at data mining drags FBI agents away from real investigations, while destroying the NSA’s credibility in the eyes of law enforcement and the public in general. That loss of credibility makes the NSA the agency that cried wolf -- and after so many false leads, should they provide something useful, the data will be looked at skeptically and perhaps given lower priority by law enforcement than it would otherwise have been given.

Worse, FBI agents working real and pressing investigations such as organized crime, child pornography and missing persons are being pulled away from their normal law enforcement duties to follow up on NSA leads. Nobody wants another 9/11, of course, but we experience real crimes on a daily basis that, over the course of even one year, cause far greater loss of life and damage than the 9/11 attacks did. There are children abused on a daily basis to facilitate online child pornography, yet I know of at least two agents who were pulled from their duties tracking down child abusers to investigate everyone who called the same pizza parlor as a person who received a call from a person who received an overseas call. There are plenty of similar examples.
