The perfect timing of the incident, all the planes were hijacked within five minutes of each other, all the planes were full of an explosive quantity of 'going all the way out to the west coast' fuel, and the success in accomplishing this without FBI interference, all Point to an elite terrorist org. not your average car bomb.
I was also very glad to know we didn't bomb afganistan. I don't want Afganies experiencing round 2 of this evil. But, If he gets away with it round 3, 4, 5, 6 , 7 , 8 , 9 , ..... are coming.
