One can see why the F.B.I. wants to keep the lid on that particular can of worms.
But one can also see why the Dem politicians preventing the release of this manifesto to the public wanted it forever kept from view because it brings into questions the mental stability of their very special minority group. This mentally screwed up 'person' hated White kids and considered them privileged . . . just like a good CRT indoctrinated leftist whacko.
