I am a retired NSA Officer, as I have said previously on this forum. I spent most of my 33 civilian years overseas an the tip of our spear. We were continually reminded of our responsibilities re the Fourth Amendment and the relevant Executive Orders. We were told that the collection, recording and/or reporting communications between US persons would lead to dismissal or prosecution. If this was being done, it was being done without our knowledge. So let’s don’t be disbanding the Agency just yet. There are still an awfully lot of bad guys out there. Ever hear of China? Russia?
