Well, when your 650+ page book covering a complex and, of necessity, somewhat speculative subject comes out, we'll see how the editing and proofreading went. But based on your track record of trying to edit a few diaries, it doesn't bode particularly well, I'm afraid.
In reading the last Harry Potter book, I found a couple of typos -- and I can hardly imagine a more thoroughly proofread book than that. Go figure.
Besides, in one place or another, I found satisfactory answers or explanations given to all the questions raised about FOTR . . . and some of those explanations were actually, "it was an error". Even after the authors departed this forum because of the tarring-and-feathering campaign, the Forum Administator and others stepped in with perfectly reasonable answers to some of the continuing challenges. And once I undertook to really dissect the challenge about the mtDNA findings and Sykes that so occupied your attention, the challenge itself seemed unsupportable.

But, if you'd like, I'll be glad to stick with the question of plagiarism. Since it is now the admitted avocation of your chief co-assailant on FOTR, I really think it's worth exploring the question of how an admitted (and apparently proud) academic cheater attains the moral high ground to claim any other person has played fast and loose with facts.
