Please, while you may have a strong opinion on what may or may not be allowed by our former US Constitution, attacking another Freeper like this does not advance your view.
I dislike (to be very kind) what the TSA does at airports to the point I have not taken a flight in 4 years but I will not attack any Freeper who believes the TSA's actions are Constitutional. I simply disagree.
In reality, a list of phone number A to phone number B does not even pin down which citizen made the call. Further investigation would be required and I assume you and I would be on the same side of the privacy fence in said investigation. We would want warrants to investigate who physically was on Phone A when speaking to the person on Phone B.
I'm sorry, but when someone is being that obtuse, either deliberately or by accident, my comment fits. And I've been called far worse on this thread.
