You and I are not that far apart on this but maybe I can better explain to you my point of view.
The collecting of just numbers does not, IMO, mean citizen Joe Bag-O-Donuts spoke to Diaperheads-R-US. It only means SOMEONE (anonymous) placed a call from phone number A to DiaperHeads-R-US. While that may seem like a find line distinction and hopefully not like the meaning of "Is", I do believe it is lawful. However, given the complexities of the current laws so poorly written that even the USSC cannot completely agree, I could be wrong.
Where you and I join company is once the government tries to place Citizen A with phone number A. Then I would agree some sort of warrant or subpoena MUST be involved.
Cheers!
It's more than numbers. These are calls. And that is data that should only be provided to the government with a subpeona or some kind of due process.
I work with connecting the dots for a living - I work with large corporate marketing databases. I know what can be done with this kind of data. But I don't have powers of arrest - all I can do is annoy you by selecting you to get some mail you probably don't want anyway. Government needs a higher threshhold to get this data, given their powers and the history of government abuse of powers. That is why we have a Bill of Rights.
