I can only assume that P Trembath considers it highly unlikely that scientific evidence and irrefutable observations are to be presented to the American Public .... ever.
Actually, I believe that the "evidence" presented to us by the conspiracy theorists is nothing more than schoolboy science, badly interpreted, and incorrectly used.
The whole thing is now nothing more than a mildly amusing bad taste joke.
Most of this junk is being plastered all over the Internet by disaffected Americans, who have a grudge against their government, and are attempting to grasp at anything they can that they think will help discredit that government.
These people need to realise that CSI, The X Files, Supernatural, Buffy, are just entertainment. Dan Brown and co, write books of Fiction.
These people need to get out more.
Right, the 9/11 "Conspiracy".
Firstly, is there one?
Did Bush Jnr, or some other person or persons, decide that they needed to provide an event that they could use to justify to the American public, and the world at large, America starting a war?
Maybe, it has been suggested that America was aware that the Japs were intent on destroying the Pacific fleet in Pearl Harbour, but allowed it to happen so that they then had the excuse they needed to enter WWII, so it is not out of the realms of possibility that elements of the American establishment would consider something similar.
So now, we can accept that such an event is possible.
But, these people, the ones behind the scenes, are reasonably intelligent people, even if they are American. They will have sat down and arrived at the obvious conclusion that for such a scheme to work, they need to be able to distance themselves from it. Their involvement needs to be deniable.
They would know that it is imperative that as few people as possible are aware of the plan, as few people as possible are involved in the setting up of, and the execution of, the plan.
Therefore, any form of pre-arranged demolition would be extremely risky, with the amount of people that would be required to prepare the buildings, the time it would take. So unless you wish to suggest that all the workers involved were all victims of the day,...........Someone would have bragged about it by now.
Therefore no hidden explosive devices, no "secret weapons", nothing. All we are left with is 1 aeroplane crashing into 1 building, twice, ( Ok, and 1 near miss, and one total, don't even know the target, miss).
This being the case, is it that far beyond the realms of possibility, that some element in the CIA, or similar, was able to egg on a group of insane religious fruitcakes, with an intense hatred of America, to hijack 4 planes, and then crash them into buildings, even suggest which buildings would be the best targets, help ease their way into the USA, and maybe even arrange an exercise that would remove any military aircraft from the intended target on the intended day.
No need for fantastic remote controlled airplanes, or anything other than the previously mentioned religious weirdos.
If you were to tell me that that was what happened, then I could be persuaded to believe, it is plausible, possible, do-able.
Now here's a real conspiracy theory for you:-
Bush and his mates did arrange the events of that fateful day, in just the way I described above, but now faced with a growing public disbelief, have decided on a policy of misdirection. They not only permit the inane ramblings of the so called "Truth seekers", but also slip them a tasty bit of misinformation from time to time, just to keep the inquisitive away from the real truth.
