Back in the day when the phone office had mechanical switches, any approved technician could eavesdrop on any call going through that office by physically hooking in to the signal. It was called, "Quality Control." Yeah, sure: on your ex-wife?
So I am not surprised that there were many loopholes in the wiretap laws; we are just seeing the logical next step of total inclusion of all transmissions. This is the vision of TIA, or Blue Sky. And remember, the "yes set" is safety from terrorism. Maybe the next red flag phrase will be "against the New World Order" ??? :-?
