This is an article from the Guardian highlighting the comments of former FBI counter terrorism agent Tim Clemente. This seams to confirm other reports we have read that ALL digital communication in the US is recorded!

"The real capabilities and behavior of the US surveillance state are almost entirely unknown to the American public because, like most things of significance done by the US government, it operates behind an impenetrable wall of secrecy. But a seemingly spontaneous admission this week by a former FBI counterterrorism agent provides a rather startling acknowledgment of just how vast and invasive these surveillance activities are."
