Not to wear tinfoil but it sounds like a Law Enforcement dry run for bigger operations. .gov is "testing" to see how their methods are going to work in real life, if things will stick, how the public reaction to be.
When the horse bolts out of the barn, you better have to grab a pre-tested lasso before data gets to far out.
No one will admit how much data leakage happened since the late 90s with p2p flooding data out of .gov, R&D, and medical offices in the West.
You don't think the intel community never caught on? Lives and reputations are continuing to be be jeopardized with wikileaks... you think people are lying around for it to just happen to them?
Likely a lull as they regroup see how to improve things, then another round.
Politicians & Bureaucrats are not techies, but they tend to hire really smart companies and individuals for consulting and executing their work.
Similar methods which today were used to down some .mp3 or girlie picture site will be in the future be used to down leaked data out of Gov, IBM, Apple, Boeing, Dow Chemical, ....

If the US .gov goes out of control it is because of the citizens of the US, past and present actions, not because of anyone's future action.
Why was I groped at the airport? Someone who was elected or appointed by someone elected perceived a credible threat of real person(s) who can't be identified and "found." instituted a response to that. Whoever that person who wants other people to be hurt or die for whatever reason; will use whatever means and opportunity they have to do it. That is a situation of intractable security.
From a classical point of view; its means, motive and opportunity. US citizens can only react to means , increase/reduce opportunity and fuel or dowse the motivation for any kind of activity criminal or otherwise.
When was the last time anyone asked "why somebody needs a new 32-64GB for their videos, pics & songs?".. that's a whole lot of cash on top of the equipment -- I'm sure they could produce each cassette, cd, dvd or print magazine and the receipts proving they bought license it and they didn't DL it off somewhere for free.
We have met the enemy and they is us - greed, apathy, indifference, do it as long as nobody's hurt or if the "Big X" gets hurt even better. Enough of this kills a Constitutional democracy (big C little d)
