I have my own suspicions -- which I won't go into here -- about what PRISM was actually about. I'll just say that there are ways to intercept people's Google, Facebook, etc., traffic in bulk without sticking any moles into the org -- or directly tapping their lines. You may find some interesting hints in the leaked PRISM slides [1], especially the second and fourth ones shown there. The subtleties of phrasing are important, I suspect, not because they were trying to be elliptical but because they reveal what was obvious to the people who were giving that presentation.
And like I said, I have both some reason to believe that there aren't such devices inside Google, and that the PRISM slides are actually talking about a somewhat different kind of data collection -- one that's done from outside the companies.
Any ideas what he could be thinking?
