Many things are claimed to have changed. Such is the narrative structure of this theatrical event. The laws of physics, for one day only, took a new form. The elementary principles of justice, well, that's an altogether more thoroughgoing and long lasting change.
What these two things have in common is that they are unchangeable. Justice and true science are no respecters of person. It is the enemies of these concepts who seek to corrupt them, to replace them with different ideological constructs under the name of the old.
This is no starting point, but these are things we can be sure of. That makes this a good place to start an investigation. If things really didn't change on "9/11" then two areas of interest arise: 1) the continuities in events from before to after the great day and 2) the reason for these untrue claims.
The official story is untrue. It's a coverup and the natural assumption, which I have every intention of making and proving, is that those engineering a cover up have something to hide. Something rather big. Certainly bigger than incompetence. Much bigger than shooting down Flight 93, which could easily have been spun as an act of toughness and defiance. Maybe even a sacrifice, to appeal to the unclean subconscious pagan/telluric realms of the public mind.
The coverup, truth be told, was inplace (as are all good coverups) long before the event to be covered up happened.
So this is how I'm going to approach it.
Firstly, we need to look at the political reasons behind it. 9/11 as catalysing event for foreign policy manipulation. Secondly, we need to look at the ritualistic aspects which are integral to both the reasons for the attack and the oddities about its execution. Thirdly, the physical evidence and fourthly the individuals directly responsible for the attack and the infrastructure that made in possible.
