The point is how we got to those contradictory stories.

In a disaster like this, government should have bought up gigantic fields outside of New York, and taken all the parts of the Towers and Bldg. 7 out there for complete examination, just like they do in any jet liner crash. And this should have been even more important that any other jet crash that was ever investigated.

The point isn't what we don't know. We know enough. The point is who did the cover-up and why.
