"I didn't suggest that Bush and Bin Laden colluded. I asked you to prove that they did not."

Sorry, but that is not how it works....no one is REQUIRED to prove a negative. *IF* you make an assertion or claim, then YOU must prove it IS true. If you are not making any assertion, then no one has to prove anything. I could 'suggest' the possibility that 'maybe' Kofe Annan hired the Pope to mastermind the plot, but how much trouble woud you go to to prove otherwise?

I saw just the other day detailed explanations on a minute by minute basis of how the hijackers got away with the plot! Several of them set off alarms at gates, but were allowed to board after a cursory search! They had JUST enough pilot training to steer the thing and to SHUT OFF THE TRANSPONDER which allows traffic controllers to 'see' where the planes are! THAT'S how they were able to, with the element of surprise, fly 3 or 4 planes to a target! It was a combination of luck and carelessness and good guesswork....At that point, we hadn't fully comprehended the notion that a group of men would COMMIT SUICIDE in order to harm us!

Isn't that a more reasonable explanation than cockeyed conspiracy plots?
