Which brings us to my point in post 13. I would think that one could sue the phone company for recording your voice communication as an invasion of privacy.
I would think part of the agreement would be the government would insulate the phone companies from lawsuits.
Besides, anything broadcast can be intercepted by a third party.
Besides, merely recording a signal isn't the same as eavesdropping, if you only passively record it and don't listen until you've decided to put a particular person under an electron microscope...
