While explaining how they did meta-data connection maps based on phone connections and internet ones a I noticed a major nit that could have negative impacts on all of us.
They make connect-the-dot meta-maps of incoming and outgoing calls email and such. But, I have been perplexed by over a decade by the number of phone calls where the caller hangs up the instant you answer. This implies that terror/spy types could have machines making lots of calls just to create noise in the meta-maps made of them, hiding their communications in the noise.
On the obverse side of this those of us who get a call become "people under suspicion". For me becoming "under suspicion" due to spam calls is chilling. Taking it further if the folks are AQ one could expect them add folks like Rantburgers to their spam call list just to put them under a pall.
The question nobody posed to the NSA guy was are unanswered calls in the meta-maps? This could put you under suspicion even if you screen all calls with CallerID.
Then the email issue. How much of that SPAM email is spys and terrorist generating digital noise and putting us under suspicion?
