Thank you, Steve. Redlich was an interesting character indeed. Too summarize in general an interesting episode, Gerald Ford had brought up the idea that ideologs from either the right or left shouldn't make up any members of the counsel. An influential member of Ford's Michigan House District brought it to Ford's attention that Redlich had been the co--author of an article in a leftist magazine or publication that went too far left and Ford almost had Redlich removed but was outvoted by the majority of the other commissioners. It turned out that Redlich's name had been added without his knowledge and he was not one of the authors. I'm writing this from memory from the book A Cruel and Shocking Act that I read years ago so don't quote me for exactness 
Yes, I'm familiar with that controversy too. Ford did indeed, at least from what I read in the same account you mentioned, apparently try to get him removed. Redlich was, well, he was a leftwinger and not a liberal. He thought the Rosenbergs and Hiss were innocent. Or at least they shouldn't have been given the death penalty (which he opposed throughout his life). As to Hiss's innocence: What was he thinking?
Re Shenon's book: it's a pretty good overview of how the WC was formed and worked.
These were honorable men in a difficult situation. Sure, legitimate criticism of the investigation can be made; it was a product made by humans: what do people make that is perfect? But the claims that they deliberately covered things up is simply not, for me, true.
