I think that's naive at best. The big point about the current direction the surveilance is headed is that it's not even targeted: it's just a sweep of all the bits at all the places that are available. That phone call you made today will not be the subject of an investigation. But it will be available in the future, when you do step out of line, in whatever way you will.
And you will.
Yes, Yoshie: it IS your problem.
