He's innocent of 9/11.
He's guilty of a second wave attack, probably using cropdusters.
He admitted he was to be used in a second wave attack.
Dept. of Justice dropped the cropduster allegations from the charges - they conflict with the theory he was the 9/11 "20th man."
If govt. loses the appeal, they'll dismiss the charges for good.
Wouldn't want to worry us taxpaying folks about what was really going on.
IMO.
