The phrase "conspiracy theory" has been morphed into this pejorative, dismissive label for anyone who questions anything since 9/11/01. But when the two words are broken down it becomes such a simple expression:
Conspiracy = the act of two or more people planning to commit a crime
Theory = an educated guess
I do not like what the phrase has become, but when analyzed in this fashion you can see that a conspiracy theory could explain any insider trading scandal. It could even be used (as I use it) to describe the official 9/11 account because, according to the story, it involved 19 hijackers with assistance from people like OBL and KSM. Additionally, there has never been any public proof to demonstrate beyond a reasonable doubt that this story is 100% factually accurate - hence a THEORY.
Central to the 9/11 Conspiracy Theory is the phrase "9/11 was an inside job." Those beholden to the official conspiracy theory undoubtedly are shocked by this assertion and scoff at anyone who would dare utter those words. Usually you hear assumptions like "so you think Bush did it" or "wouldn't someone speak up?" While fringe elements of the 9/11 Truth Movement may believe Bush was involved in some way, this is not the true meaning of the phrase.
I think I speak for most in the community when I say that it is not necessary for everyone inside the government to be involved for it to be considered an inside job. In fact, for the shadow government, or whatever name you want to ascribe to the moles and patsies, it is better for them if they can keep those in the know to a minimum. So, no, I do not believe Bush had detailed foreknowledge of the attacks - Presidential Daily Briefings aside. Honestly, he is far from intelligent enough to handle such information in my opinion. All they needed were people placed in strategic places to confuse and alter protocols just enough to pull of this horrific attack. "9/11 was an inside job" serves as a provocative expression to get people's attention, but the real story is much more complicated.
