they did know of it, they had written threats from these people. supposedly that is. but i believe the us govt took those buildings down to gain support for the war. just as they did in the past.
3 buildings don't fall into their own basements in perfect neat piles and one of them wasn't even hit by a plane and it just comes down at free fall speed. look at the molten metal in the basements 6 weeks later, jet fuel does not melt steel like that. i work in an oil refinery that has had numerous explosions. shot a whole flare tower, 200' tall, over a mile away, and worst they had was twisted and contorted ibeams which are nowhere near the size of the beams in those buildings. and yes, it is jet fuel, the refinery i work at makes jet fuel and very high octane racing fuel. look at the ibeams sticking out of the wreckage in the videos all with perfect 45 degree cuts with slag all over them from where the thermite cut them. if the so called "terrorists" blew them buildings up then why is our govt lieing to us saying planes took them down.
they think we are all stupid. they think we're not paying attention and they got away with it. too much technology today, this isn't another jfk. there's enough video and internet access and common sense. ask yourself why the building 7 fell when it wasn't even hit by a plane. how did the buildings disintegrate and why did they immedietly take all the steel out into the ocean and melt it down. all evidence destroyed as fast as possible.
bottom line, keep spreading the word about ron paul.
