In post 4, shaman_ argued that conspiracy theorists want to bring up people like Barnett and Asteneh and their qualifications but ignore the conclusions they reached.
In point of fact, I have never ignored the conclusions they
have reached. Astaneh-Asl's conclusions were tentative, however:

Astaneh resigned from the investigation team put together by the Federal Emergency
Management Agency and the American Society of Civil Engineers because he didn't
agree with the group's decision to keep findings secret until the initial inquiry
was complete. Without FEMA's backing, the National Science Foundation team was
shut out.
