We already quote Barron prominently in the lede for his opinion on the matter. I see no particular reason to alter that. I am glad that you have accepted that there is no absolute academic consensus regarding Hiss's guilt however - am I right in assuming that you will therefore no longer be asking for the article to claim in Wikipedia's voice that the notes from the Soviet archives prove Hiss was guilty? It would be entirely illogical to do so, as I see it.
