The letter instructed the company to never disclose the existence of the demand to anyone  in particular, the target of the investigation. This sort of letter is not uncommon post-9/11 and with the passage of the U.S. Patriot Act, which gave the FBI increased authority to issue so-called National Security Letters (NSLs). In 2010, the FBI sent more than 24,000 NSLs to ISPs and other companies, seeking information on more than 14,000 individuals in the U.S. The public heard about none of these letters. But this time, the company that received the request pushed back. It told the agency that it wanted to tell its customer that he or she was being targeted, which would give the customer a chance to fight the request in court, as a group of Twitter users did last year when the Justice Department sought their records under a different kind of request. The minor defiance in this latest case was enough to land the NSL request in a federal court docket last Friday, where the government filed a request for a court order to force the company to adhere to the gag order." ...........
