Any suggestion that WTC7 was pre-rigged for demolition is a tad insane... while they may or may not have pre-rigged it, the amount of damage it sustained and was likely to sustain if we even did assume there was a conspiracy theory for the attack on the twin towers, would have meant that any pre-rigged demolition would not have gone off even close to plan and almost deffinatly not resulted in as neat a collapse as happened.
