There's a fascinating interview at Wired today with the AT&T whistleblower, Mark Klein, who exposed the blanket FISA-unapproved NSA spying on US citizens authorised by the Bush administration.
"WN: What made you decide to go public?
Klein: 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.)
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."
