US government invokes 'special privilege' to stop scrutiny of data mining

It should be noted that the state secrets privilege was created in the cold war period in http://en.wikipedia.org/wiki/United_States_v._Reynolds.

Following the declassification of the data many years later, critics have concluded that the government asserted it fraudulently. Certainly it seems likely that it has been asserted fraudulently since. And its use has increased over time.

Nothing new in this one.
