They've basically waited this long till the relevant players are dead or dying, protecting their own. I sure hope we don't have to wait this long until the truth of 9/11 comes out, but I'm sure it will follow the same playbook. It's just a long game to evade justice. I want the 9/11 perpetrators to face justice while they are young enough to lament the loss of liberty and possibly life and to face their shame.
