Re: Destroyed All Braincells Please adopt this notation
It appears that the FISC court is also known as the FISA court, and has been since 1978 when it was created, so the distinction you have made in calling it solely the FISC court is incorrect.
Also, whilst mr. Greenwald may not be a legal expert, let's listen to the findings of the 2003 Senate Judiciary Committee Interim Report on FBI Oversight in the 107th Congress by the Senate Judiciary Committee: FISA Implementation Failures, who most certainly do know the law, and reported;
"The secrecy of individual FISA cases is certainly necessary, but this secrecy has been extended to the most basic legal and procedural aspects of the FISA, which should not be secret. This unnecessary secrecy contributed to the deficiencies that have hamstrung the implementation of the FISA. Much more information, including all unclassified opinions and operating rules of the FISA Court and Court of Review, should be made public and/or provided to the Congress."
Or to former National Security Agency analyst Russell Tice who called it a "kangaroo court with a rubber stamp"
Furthermore, On May 17, 2002, the court rebuffed then-Attorney General John Ashcroft, releasing an opinion that alleged that FBI and Justice Department officials had "supplied erroneous information to the court in more than 75 applications for search warrants and wiretaps, including one signed by then-FBI Director Louis J. Freeh." Whether this rebuke is related to the court starting to require modification of significantly more requests in 2003 is unknown.
On December 16, 2005, The New York Times reported that the Bush administration had been conducting surveillance against U.S. citizens without the knowledge of the court since 2002. On December 20, 2005, Judge James Robertson resigned his position with the court, apparently in protest of the secret surveillance.
Elizabeth Gotein, a co-director of the Liberty and National Security Program of the Brennan Center for Justice at the New York University School of Law, has criticized the court as being too compromised to be an impartial tribunal that oversees the work of the NSA and other U.S. intelligence activities. Since the court meets in secret, hears only the arguments of the government prior to deciding a case and its rulings cannot be appealed or even reviewed by the public, she has argued that: "Like any other group that meets in secret behind closed doors with only one constituency appearing before them, they're subject to capture and bias."
A related bias of the court results from what critics such as Julian Sanchez, a scholar at the Cato Institute, have described as the near certainty of the polarization or group think of the judges of the court. Since all of the judges are appointed by the same person (the Chief Justice of the United States), nearly all currently serving judges are of the same political party (the Republican Party), hear no opposing testimony and feel no pressure from colleagues or the public to moderate their rulings, group polarization is almost a certainty. "There's the real possibility that these judges become more extreme over time, even when they had only a mild bias to begin with," Sanchez said.
Or, how about a quote from someone who was actually ON the FISC? James Robertson – a former judge for the U.S. District Court for the District of Columbia, who, in 2004, ruled against the Bush administration in the Hamdan v. Rumsfeld case, and also served on the FISC for three years between 2002 and 2005 – said he was "frankly stunned" by the newspaper reports that court rulings had created a new body of law broadening the ability of the NSA to use its surveillance programs to target not only terrorists but suspects in cases involving espionage, cyberattacks and weapons of mass destruction.
I think it's safe to call those persons quoted experts, and it is therefore reasonable to entertain their criticisms.
All of these points come from the same Wikipedia article as the one you have quoted from: http://en.wikipedia.org/wiki/United_States_Foreign_Intelligence_Surveillance_Court
