If you´re not paranoid...
... as someone clever once said... you are not paying enough attention :-)
I honestly don't think we will ever hear the last word about what happened on 9/11, so it's fascinating for me to see the Paranoiacs duke it out with the Orthodox Church of the holy Official Reports.
As the last ones go, there are most likely truth to the point that most conspiracy theories stem from an ingrown disdain for the government, but on the other hand, no-one can reasonably argue with the fact that the laws passed on the basis of 9/11 (Patriot Act, Terror War and all) has given good ol' Dubya a carte blanche to do pretty much whatever he likes largely unopposed by the American people or, for that matter, the rest of the world.
I don't personally think that 9/11 was the result of a carefully planned conspiracy, because, as Tom Clancy himself put it, if the U.S Government was that efficient, how come the hurricane relief for New Orleans was such a mess?
But one should keep a keen eye on what someone in charge can get away with whilst the rest of the nation looks for bearded men on airplanes and white powder in letters.
