34,000: The number of law enforcement and intelligence agents who have unfettered, virtually limitless access to phone records collected through NSLs.
11,100: The number of different phone numbers whose subscriber information was turned over to the FBI in response to only nine NSLs.
43: The number of confirmed criminal referrals made to prosecutors from the FBI after it obtained information through a NSL. (19 involved fraud, 17 were immigration-related and 17 were for money laundering.)
