NY Times have now sued the federal government for not revealing its interpretation of the PATRIOT Act, pointing out that if parts of the interpretation contain classified material, the Justice Department should black that out and reveal the rest, but simply refusing to reveal the interpretation entirely is a violation of the Freedom of Information Act. You can bet that the feds will do everything they can to get out of this lawsuit, just as they did with the various lawsuits concerning warrantless wiretapping.
This will be an important case to watch. An unclassified law with a classified interpretation appears to be a pretty egregious misuse of the classification system for the mere purpose of witholding information from the public.
For a president who promised a new era of transparency, Obama has a pretty shitty track record even though his administration continues to be lauded for their work on this subject. Someone needs to open their eyes and see the damage they are causing the nation - damage rivaling GWB at this point.
