Precisely what grounds are there to dismiss the NIST report or the structural collapse theories of the hundreds of other professionals? Why is there disagreement between the different groups contesting the conclusions reached by the 9/11 investigations? Why is there disagreement about whether airplanes hit the towers, when videos clearly show that to be the case, and similar videos are used to validate other parts of the conspiracy theory?

The article points out 4 main points of contention.
  1. Fall time for WTC 7.
  2. Fall times for the Towers.
  3. Challenging the NIST report and Fact Sheet.
  4. Evidence for use of Thermate reactions: What the WTC dust and solidified metal reveal.
These points are not in the least bit conclusive, and there are weighty counter-arguments for each of them. Is point 3 based upon an honest review of the NIST report? Can we trust those who distrust the NIST report to give an objective and careful review of its conclusions? Point 4 is compelling, but equally plausible alternatives have been mentioned, and it fails to explain some basic questions.(Why would thermate be used instead of conventional cutting explosives?)
