jet fuel wasn't the only thing burning.
No, it wasn't, but it is one of the hottest burning substances. Paper didn't increase the temperature of a jetfuel fire, nor did the desks/walls/etc.
The thick black smoke that was pouring from the towers also indicates a suffocating fire.
Fire fighter tapes indicate that the flame would've been knocked out with two hoses.
Watch any video of the towers falling and tell me you can't see the demolition squibs (looks like dust shooting straight out of the side) below the accumulation of falling building debris.
Not wanting to turn this into yet another 9/11 thread
True, there's plenty of those.
The whole occupy thing, I would agree with foothead on this; they should have indeed been more structured with their list of what they would like to see accomplished instead of blindly protesting.
