"Six months before, we got a notice from the San Francisco F.B.I., saying they were going to give us a national-security letter [...] And we couldn’t figure out why they would say they were going to give us this letter! Kind of an odd thing to do [...] And they didn’t give us one, not at that time. It was later that they did." This is a fascinating glimpse into the logistical aspects. Either the FBI was trolling to see if they'd roll over easily, or they were baiting them into some kind of reaction. I wonder what would have happened had they gone super public with their "we plan on NSLing you" notification?
