What got me back interested was The New York Times' story in December 2005. (Editor's note: The Times reported that the government had been secretly monitoring Americans' phone calls and e-mails that crossed the nation's border since shortly after 9/11 without getting approval from the Foreign Intelligence Surveillance Court, or FISA.)Link
The president admitted the program existed, but only admitted that part which had been exposed -- and he avoided talking about the part that wasn't, which was the internet.
The administration sent officials out to defend the program, including (Vice President) Dick Cheney, and they said they didn't think they had to obey FISA.... This was the defense of the indefensible. So I decided if they are going to perpetuate this fraud then I'm going to blow their cover.
