I have already stated that the motive is unknown and probably unknowable without subpoena power. The 9/11 Commission had such power, but failed to exercise it with regards to WTC-7. Profound statement Lovehound: Absence of proof proves nothing. Perhaps that's what was on the mind of the 9/11 Commission when they didn't investigate the collapse of WTC-7. Your comparison of the collapse of WTC7 to a magic show is spurious and actually supports my hypothesis. It is the people involved in a magic show, the performers, that purposefully act in such a way that your eye is deceived. Everyone here is arguing that well understood principles, namely gravity, worked to bring down WTC-7. I'm the one that is arguing the possibility of human involvement. Also, your argument that "Things often look like what they are not" actually lends support to those earlier that were trying to get everone here to not believe their eyes, that two jets crashing into WTC 1 and 2 were the only cause of their collapses. Which is it, do we beleive our eyes or don't we?
