I read a recent history of the NSA, that covers up until the mid-70s ... so I already knew this, in old style print. What the police state has now is just a technical update from what they had in the 70s, when they promised to stop doing what they were hired to do. The funny thing is, for the last 40 years, so many schlubs have believed their promises. Even the modus vivendi between the US and the Soviet Union then, is still the foreign policy (Intel portion anyway) the US follows now.
I am pro-State ... so I am neither shocked nor offended. Of course most of the Intel gathered on my mother in nursing home is wasted taxpayer money, but that is most of what the State does also. It would have been interesting to hear, what the CIA heard, when they tapped Merkel's phone ;-) Does she dress up in leather? Does she whip her husband? Achtung, Macht schnell!
