Yep. Saying Times Roman was created in the 1940s, therefore it doesn't prove that the docs are fake is like saying that since the Art Deco font was created in the 30s, documents written in that font would be real, too. It's not a question of whether the font existed then; it's a question of whether it would be used on a typewriter in the TANG. And even the document Dan Rather showed to "prove" that the th was available was in Courier, not Times Roman.
Dan Rather thinks we're all stupid people out here (nee -the little people) and can't figure anything out. He is SO YESTERDAY'S NEWS. (I wish.)
