Earlier quoted context omitted.
Did you not read the Verizon order? The order that very clearly demands a daily dump of all metadata (source/destination phone numbers, date/time, etc.) for all customers, even those calls wholly within the US?
Additionally it isn;t clear to me if cell site location data generated in order to be able to enable a call would fall under it. If it does, then the order turns our cell phones into Knotts-type tracking beepers.
IANAL but it seems clear that cell site data could be included (since it's held to be transactional data), but it would be limited to the towers connected to when making and ending calls, not a complete timeline. [2]
