And what are the “sufficient resources” the government has that can anyone down, do you know?
There are electronic eavesdropping techniques I don’t fully understand, but have had mentioned by a couple intelligence types I know + the government has, for lack of a better word, “hackers” on the payroll + the ability to lean on ISPs informally; if they think they have something prosecutable they can just seek a subpoena for the information (as with the pornographers). IP traffic is logged, and though you may have a new IP assigned every session it is linked to the carrier and the carrier has records of which IPs were assigned to which customer accounts. You do get into forensics eventually, but it’s doable. The difficulty in prosecutions usually isn’t lack of information but rather difficulty in getting it admitted. None of that will matter in the event of a truly tyrannical regime. For example: http://www.slate.com/id/2221397/
