Instead of fretting about this whitewash crapola, check out Stalin: Inside the Terror, on YouTube. A BBC2 documentary from 2003.

All that needs to be said about Dalton Trumbo and his inhuman peers is that they were all in favor of what Stalin was doing, and wanted Stalinist terror in America.
If anyone deserved hanging for treason, it was these monsters, and their descent today.
I was listening to the Cranston interview on NPR. (yeah, I know. I was stuck in traffic in a radio wasteland.) What I came away with is: why did Trumbo get a year in prison for contempt of Congress, and Holder didn’t???
