So what do you do if you're a vast global adversary network of old chums, with unlimited resources, a world citizenry that is perhaps becoming unafraid of terrists as background noise, and some might say an authority to keep?

Why, sit back and spy on everyday knowledge seekers, file sharers and you tubers of course!

Wasn't that the main idea all the time? Cf.: 1. http://www.stratfor.com/obstacles_capture_osama_bin_laden tl;dr NSA-style spying doesn't really help that much in "anti-terrorism" 2. http://www.counterpunch.org/2006/05/24/why-does-the-nsa-engage-in-mass-surve... tl;dr it is statistically impossible to have profiling (based, say, on dragnet surveillance) work well on large populations -- too many false positives and false negatives. 1. & 2. can be safely assumed to be known for the NSA and powers that are. So obviously anti-terrorism is not the real aim of all this. What is? Shall we quote 2.? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Suppose that NSA’s system is really, really, really good, really, really good, with an accuracy rate of .90, and a misidentification rate of .00001, which means that only 3,000 innocent people are misidentified as terrorists. With these suppositions, then the probability that people are terrorists given that NSA’s system of surveillance identifies them as terrorists is only p=0.2308, which is far from one and well below flipping a coin. NSA’s domestic monitoring of everyone’s email and phone calls is useless for finding terrorists. NSA knows this. Bayes’ Theorem is elementary common knowledge. Also, mass surveillance of the entire population is logically plausible if NSA’s domestic spying is not looking for terrorists, but looking for something else, something that is not so rare as terrorists. For example, the May 19 Fox News opinion poll of 900 registered voters found that 30% dislike the Bush administration so much they want him impeached. If NSA were monitoring email and phone calls to identify pro-impeachment people, and if the accuracy rate were .90 and the error rate were .01, then the probability that people are pro-impeachment given that NSA surveillance system identified them as such, would be p=.98, which is coming close to certainty (p_1.00). - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Everything cypherpunks were saying in 1984 is coming true. The story continues...
