Some have suggested that the concerns raised over the official explanation of the collapse of WTC7 warrant a new investigation. What would that look like? Should it be be NIST again? How exactly do you think NIST should proceed? Or if not them, who? How should they proceed? Should they be banned from using computers? Or only use open-source software and data? What do you think should happen? You want a new independent investigation, let's say you have $100 million. How do you proceed?
