All of this “evidence” and testimony could’ve been presented to the DOJ and grand jury out of the public or hell, they could’ve aired it.
The 9/11 commission has no expectations for anyone to be criminally prosecuted. It was designed to determine how it was able to happen in the first place. And we went to war and eventually killed the mastermind and imprisoned co-conspirators.
This should be treated as a criminal investigation. People have already been prosecuted and sentenced. This should be no different.
