Read that statement carefully - NR is suggesting that Lamb has no knowledge of the recantation - but look - that is *not* what Lamb said at all - Lamb is talking about the "anonymous source" - he does not know who the anonymous source is.
He is *not* denying that Beauchamp recanted.
Oh, God, what a slimy bunch of weasels at the NR! Busted!
You're right! I consider myself fairly fluent in "parse-tongue", but you are the master.
