How do we reconcile the AUMF with an obstructed 9/11 investigation?
28 pages of the Joint Inquiry report are STILL classified because they point to Saudi involvement in facilitating the 9/11 plot.
The full CIA IG internal review report is still classified because some people in D.C. don't think it's fair to single out CIA officials and agents who failed to do their jobs properly in the lead up to 9/11. The 9/11 Commission wasn't able to get to the bottom of CIA conduct because they were either unwilling or obstructed. My source for this is 9/11 Commission legal counsel John Farmer who admitted on the record that the Commission wasn't able to determine what happened in regard to hijackers al-Hazmi and al-Mihdhar who were linked to a Saudi support network.
IMO you can't have it both ways. You can't as a powerful US government official tell the public that they must make civil liberty concessions based on the lesson of 9/11 while completely blocking off avenues of investigation and accountability because they might upset some people. Yet that is the very situation the public has been told makes sense. If a citizen acted as government officials have they would be charged with obstruction of justice and accessory after the fact.
