Every year, the FBI sends about 50,000 "national security letters" (NSLs) to Internet service providers and others requesting information about their customers. Today we filed a lawsuit aiming to make sure that the government is following the rules when it uses this controversial tool.
NSLs allow the FBI to collect information that's extremely sensitive — e.g. the names of websites that a person has visited, or the email addresses with which she has corresponded — and to do so without judicial oversight. Unsurprisingly, government reports have detailed significant abuses.
