There are a few academics who were quoted in the original Boston Globe story about the Signing statements (the one that first pointed out the more than 750 times). A couple of them have studied signing statements made by president's over the years. Find their names, and through their Univerisities find their faculty email address. Write to them (politely, of course) and let them know that you have been trying to become informed about the content of signing statements (your example of comparing those of Bush and Clinton), but the access point to find them that you use, no longer seems to work in terms of finding the signing statements. Call their attention to this, and ask them if they are able to find the signing statements through another avenue? If they use other avenues, and those are also seemingly scrubbed, than i would contact the original writer of the Globe story and tell him what you are discovering.
Sadly I have very limited time for follow-up, and limited net access for the short term, or I would do this as well. Given the energy that you are clearly already devoting to this (thank you for doing so!), perhaps you would be willing to pursue the avenue I suggest above?
Thanks for bringing this to our attention. I read your post and gasped. It would be beyond the pall if this is the case. This is more than 'secrecy'. This is an administration trying to centralize power in ways that make congress (and the courts) more and more irrelevant. If the existence of these statements of intent (how the Admin believes the law should be interpretted) can not be read, than it can not be determined whether or not they are acting on them, and acting against the laws passed by Congress, and then there can be no Court review. The signing statements themselves, seem to throw us into a Constitutional Crisis - however with the ability to check to see if/how the laws are actually being administered (the claim by the right is bush is just stating a contrary opinion, not that he is acting on it and thus there is no constitutional crisis) - is important. If these documents disappear as well, we might as well live in a dictatorship. The term 'coup' that was thrown around in 2000 at the point of the Supreme Court ruling in Bush vs Gore - takes on stronger and stronger implications. With that in mind, I hope that the documents in question have just been moved - and are still able to be found rather than having been scrubbed.
Thanks again for sharing and pursuing this.
