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.
We have snakes in our midst, yet we are chasing a mythical beast with completely unreliable evidence.
Chasing a mythical beast. Nice.
