During the early 90s I worked at Cylink, a Crypto AG competitor. We too
   received a NSA visit about weakening products sold to certain clients
   (e.g., so-called narco-terrorists). I and the other directors were told
   of this (because we had legal responsibilities and liabilities) at a
   meeting. I assume we made the changes requested (e.g., weakening the
   RNG to NSA specifications). The special units were sold through a
   selected distributor in Louisiana (probably also a NSA contractor).
