And international traffic should be.
But not domestic traffic where both ends are in the US. That’s where the NSA has gone to far.
Yup... I was only involved in international traffic but systems like Carnivore was instituted in England by a joint venture between the CIA and British Intelligence.... Carriers routed some of their domestic traffic via a hub to Great Britain where British Intelligence could look at the content ( not CIA) and legally monitor us citizens.... Then they could legally share the info with the CIA since foreign intelligence agencies can share info....
This kept everyone legal ,,,,, unethical in my opinion ,, but legal,,,, using foreign intelligence agencies to spy on Americans,,,,,
