NSA likely had the contents of the PRN server long before it was exposed.    The SAP program was very possibly moved or racked up with the servers which went to Benghazi.  Airs gapped - never on a network.  The staged "protest" and subsequent activities were the cover needed to go in and steal the server with the SAP info. Most likely, it was in a flypack (roadcase) and the threw it in the back of the truck.    It would explain why a QRF, air or otherwise, was ever dispatched (stand down order). It also explains why all the heroes involved on the ground were shit upon by HRC/State and Hussein.
