This is the US of A, after all, the "land of the free" with Patriot Acts galore.
A classic case of "plausible deniability" - what else would they say to the public? Or do you think agencies like the CIA also admit publicly to having secret prisons all over the world?
"Oh yes, we got this information as part of our secret national security efforts"?
Gimme a break, Sirs. Hackers are the harmless factor here; it's the FBI and other illegally-mandated agencies that have a lot to respond to the usually-benighted US citizens. And I am sure we will still read here some supportive comments stating that "No problem, they must have had some fine reason for doing so; after all, they fight every day to save our poor lives".
