The apparent purpose of the questioning was to create a snappy YouTube. Looks like a success to me -- especially if one can accept the premise that Larry Silverstein, in 2002, inadvertently admitted that he had had WTC 7 demolished, with an incoherent cover story about how he discussed it with the FDNY first.
Here's my attempt to transcribe part of that question (the most question-like part):
...it's pretty clear that you meant the building, and if it was the firefighters, they are already outside the building by 12 because the water lines were broken, and the fire chief that you said you spoke to, Fire Chief Nigro, denies talking to you on that day of 9/11. Can you answer those questions and (????) the theories against you?
(1) It's not at all clear that he meant the building. Silverstein said, apparently referring to the FDNY, that "they made that decision to pull." Why would anyone assume that that meant that FDNY decided to blow up the building? (Or that it
really meant that Silverstein decided to blow up the building, and thought it would be a good idea to go on camera the following year and blame it on FDNY?) What evidence is there that "pull" is commonly used to refer to blowing up buildings, and why would Silverstein use the expression on camera?
(2) The questioner gives no basis for his assertion that all the firefighters were out by 12, and other accounts indicate that the decision to remove the last firefighters was made at 2:30 (as per the NIST report) or later.
(3) As far as I can tell, Silverstein never did say that he was talking to Nigro. There was more than one commander at the WTC site. Even if he did explicitly misremember who he had talked with, what would that prove?
Or, more concisely: that's dumb.
So, what was Silverstein supposed to tell the questioner, anyway? It seems that a fair answer would have been, "Frankly, if you think I had the building blown up, nothing I say will change your mind, and I think that's sick." All in all, his answer seems remarkably polite.
After Silverstein gives his answer, the questioner follows on: "Are you aware of testimony of bombs in the building before the building collapsed, sir?" That's dumb, too. What counts as "testimony," and how could it possibly matter whether Silverstein is aware of it?
It is career and often social suicide to doubt the official account of 9-11 for an establishment individual. The security of one's family and self, catapulted by the media and DC, is a valid response.
So only the fringe will state the obvious and they are loons.
The trouble is, a lot of what "the fringe" states isn't obvious at all. So before you deploy psychological explanations of why people don't admit that your arguments are right, maybe you should focus on whether your arguments actually are right.
