What the FBI can do with an NSL and a gagging order
30 Nov 2015 at 22:53, Kieren McCarthy
Following a decade-long legal battle, the details of a US national security letter (NSL) sent to ISP owner Nicholas Merrill can finally be revealed
The broad details have been known for some time, and a recent court decision all but listed the personal information that Merrill was told to hand over on all of his ISPs' customers.
However, the decision by the FBI to not continue appealing the federal court's judgment means people are now able to formally see the personal information that the US government believes it has a right to be granted access to without a warrant...
...At the same time the gag order built into the NSL was officially lifted, an unredacted version [PDF] of a court decision from Judge Victor Marrero was published listing in full all the details that the FBI requested be handed over by Calyx Internet Access back in 2004.
That PDF can be found at the following link, and is worth a detailed read not only for
what it reveals, but for wonderful levels of judicial snark:
