It's funny how people take details out of context and elaborate a complicated theory behind it.
To start with, it's not possible to plan an operation like this, I mean, from the point of view of the US government.
Yes, the terrorists did it, but that was the easy part.
But think for a minute, the US government making a group of muslim terrorists believe they were working for Bin Laden while in fact they were working for the CIA, or better, there weren't muslim terrorists but CIA agents and chose to die to support Bush's lies
Then, they needed to have the FBI, the NSA, the CIA, all of them blind.
Of course, nobody let any detail be known, of the hundreds, and all the details worked out pretty well, everyone did its part and now the US government have hundreds of people that know a secret that could bring the government down.
Of course, all these evil politicians took an impossible risk (can you imagine the consequences if this was known) just to invade Afghanistan.
Really people, I don't say you stop watching TV, but if you are watching 24, please realize it's fiction.
