An anonymous author (they cannot legally reveal their identity) describes their National Security Letter gag order. Since the Patriot Act, the FBI has been sending out tens of thousands of these Letters, the recipients of which have no choice but to comply and keep absolutely quiet about it. "Living under the gag order has been stressful and surreal. Under the threat of criminal prosecution, I must hide all aspects of my involvement in the case — including the mere fact that I received an NSL — from my colleagues, my family and my friends."
