PBS Frontline's "Spying on the Home Front" last night was downright chilling. Although there were no major blockbuster revelations, they painted a very clear and complete picture of the Bush administration's vastly expanded domestic surveillance programs and their impact on civil liberties. This clip shows how Alberto Gonzales was very careful during his Senate testimony on the NSA warrantless wiretapping program exposed by the New York Times in December 2005. On numerous occasions he made it abundantly clear that he was only testifying on that specific program, which leads one to conclude that there are likely other (and more intrusive) domestic spying programs in place. Indeed, when Sen. Feinstein asks him if there are any other programs, he literally says "I don't know how to answer that."
In case you missed it, I highly recommend watching the entire thing on the PBS website. This is by far the most comprehensive report to date on the extent and severity of the Bush administration's post-9/11 domestic surveillance activities.
