Thanks zebra2. Which questions do you feel are unanswered?

Richard Gage doesn't answer the question of why because that would be speculation and therefore conspiracy theory. He's approaching it from an evidence point of view. If we knew why, there would be no controversy. But just because something seems implausible, it does not mean it's impossible specially if we don't know the full story and motivations.

...why involve the large number of people needed to orchestrate a demolition...

That's an assumption you're making. We don't know how many people it would take to plant those sophisticated termite charges, apparently they're a lot smaller than regular explosives. And who's to say that every modern high rise isn't already pre-wired during the construction phase just in case it needs to be brought down in an emergency? I don't really believe that, I'm just speculating to show you that there might be avenues which we cannot see since we don't have the full picture. Hence the importance of a full independent investigation.

I might instead buy the idea that, rather than a conspiracy, the was gross incompetence...

Incompetence would be a lot easier to swallow but sadly it doesn't really go with the evidence of the building's symmetrical collapse.
