I can entirely understand your skepticism here, and to a large extent share it. The good people who are calling into C-Span to raise awareness to the issue of the NIST omissions in their WTC7 report are performing what as a non-american, I would consider their patriotic duty, and I join you in applauding their efforts.
As far as the issue itself goes, the cat is out of the bag, so to speak. NIST have misrepresented what is in their own analysis, the critical connection in the initiation of the buildings collapse. No amount of back peddling on their part is going to change the contradiction between the structural drawings that THEY released, and the report that THEY released. My personal feeling is that they did not "cleanse" the FIOA release which allowed us to shine the light of scrutiny on their "error", as much as they intended.
This hugely important detail was a needle in a haystack, and that kawika found it, is a testament to his diligence and determination to hold NIST to account. Whilst like you, I do not expect Mr Soros, or any of his cronies to be particularly helpful in bringing accountability, what I do know is that we can make sure that those of his ilk are conspicuous by their absence in this matter. Also, I like your analogy with the grand piano, because what we are trying to do here is the equivalent of throwing one a very far distance. But I do believe that together, we can do it. I have moved a few pianos in my time, and they're not always as heavy as you think. One thing is for sure, if we do not take a hold of it, it won't move itself. And if we can use organisations such as these to help gather a crowd around the piano, then the load will be lighter and it will be moved all the quicker.
