Richard is being a total hypocrite here.
Richard makes no bones about the fact that his ancestor Captain Alfred Dreyfuss got a raw deal, and that the official version of the Dreyfuss affair should have been challenged immediately to prevent a miscarriage of justice.
Now he ways there should be no more investigations of 9-11 for another generation; which is saying let the real perpetrators of the fraud get away with it.
Sorry Richard, I just lost all respect for you. You're just another Hollywood putz.
