What about A&E for 9/11 Truth that found evidence of nanothermite by spectrometer debris analysis? Sure, we can question their conclusions, methodology and trustworthiness etc. I don't know, I'm not a scientist and I wasn't physically there to monitor their processes from start to finish to definitively know for sure.
That's just one example. My point is that it would be irresponsible to make a blanket assertion that there was "no evidence" when clearly there is, regardless of what we individually choose to believe is true or not.
For me, the thing I have the hardest wrapping my head around is the near free-fall speed and symmetrical collapse into the footprint of all three buildings. Again, I'm not a scientist but I would expect the top-half of each building to kink at the asymmetrically damaged areas and topple over, with minimal damage to the lower portion. Or, at the very least visually witness a rapid deceleration of collapse that is easily reproduced with a basic experiment of physics (Example: here).
I have yet to hear a convincing argument that explains these anomalies.
If men are good, you don't need government; if men are evil or ambivalent, you don't dare have one.
