——The NSA has all of this data captured -—
No, that is incorrect by a very long shot. an I phone is a computer with a telephone ap. the device has all sorts of data not collectable by NSA. The wireless data transmission independent of the cell towers can transmit all sorts of very secret stuff the NSA could only dream about.
Then there are all sorts of aps with who knows what kind of records of value.
They are claiming they need to see who they contcted
(I know that)
That should scare people even more
