All your speculation and questions have been addressed or answered. But, you refused to look into it. I.e. you didn't view the videos I posed.
Also, since I am such a rude and fanatical person as accused and addressed as so, I don't find any purpose in continuing.
The author you also ignored and stated in explicit terms as suspicious because of the language some website used, has very methodically debunked the 'Debunkers.' Why would I continue when you are only picking certain areas to debate on?
I think after 10 years, most people who have read even bits and parts on 9/11 would be aware of the Debunkers page and the NIST report. Both which have been addressed by various sources.

As for the security in the building and time for explosives, this has been explained already, a long time ago:

There are also numerous sites that state that Marvin Bush was gone but there's nothing (i.e. none) to suggest he had no role.
Anyway, these are too much of a 'conspiracy' for most people so who cares, I guess.
