George Bush's brother had nothing to do with security at the WTC in 2001.Did you even read my link.It provides an extensive explanation for the collapse of WTC7 and shows that firefighters and experts did not believe that there were bombs in the WTC. Certain things such as transformer explosions , bursting rivets , buckling floors,snapping steel bolts falling debris etc can sound like explosions.What is your evidence for that so called bring it down instruction? you are not refering to Silverstein saying pull it are you ? As discussed in the link pull it doesnt mean demolish with explosives . Also the fire commander decided to pull it meaning to abandon attempts to save it because it was leaning , on fire and posed too great a danger to firefighters.Do you think Silverstein could tell the FDNY what to do or that FDNY would kill hundreds of their own ? Do you think they had nothing else to do on 911 than place explosives in a burning building?
