Spector and Gorelick really put the lid on that during the 9/11 cOmmission hearings.
All the conspiracy theories about explosions, Mosad, whatever, were often fed into by the government as a smoke screen to camouflage and cover the REAL conspiracy.....Gorelick's hiding of the ChiCom/Clinton money connections with her "Chinese Wall". Had it not been for that, military intel and FBI likely may have been able to connect the dots.
