Yea, Snowden is responsible. Because we never knew about phone monitoring before?? Glad the terrorists never watched the wire or any other police procedural going back to the 70's.
The NSA had bin laden's sat-phone line in the 90s. I've seen documentaries on it.
Snowden confirmed the extent of NSA surveillance in 2013.
So that's 12 years for which the GP's statement was true.
Advanced technologies allow them to know when these things are brewing, but per game theory they allow them to happen to not reveal that capability.
Encryption and Snowden have nothing to do with it. They are limited hangouts to gaslight and decrease the power of the lower echelons of government (you know, the regular people who might actually have stopped this).
And you know about them.....how? If you haven't realized, I'm asking you to provide a source for these extraordinary claims.
