How is there no mention of CALEA[0] in this document? They even hint at it in the Executive Summary:
Indeed, in 1992, the FBI’s Advanced
Telephony Unit warned that within three years Title III wiretaps would be useless: no more than 40% would be intelligible and that in the worst case all might be rendered useless [2]. The world did not “go dark.” On the contrary, law enforcement has much better and more effective surveillance capabilities now than it did then.
