Privacy Groups Challenge FBI Authority to Obtain Records Without Court Order
You've already seen various thoughts regarding these quite interesting "National Security Letters," including the fact that you're not allowed to say when you've received one, and if you sue over it, you aren't allowed to tell anyone until they say you can, etc. etc. Now people are attempting to do something about it.
CDT joined other privacy groups and an ISP trade association in filing an amicus brief today in support of the ACLU's challenge to the FBI's National Security Letter authority, which allows it to obtain certain customer records from ISPs and other businesses without a court order.
