Yes, I read the article. While no specifics were given, the fact that Ford's Theatre banned it is pretty strong anecdotal evidence that BOR did a lousy job.
From the WP article: ‘Other Lincoln experts also have sounded off. In a review published in the November issue of “North & South — The Official Magazine of the Civil War Society,” historian Edward Steers Jr. cites many instances where the book strays from documented history, then asks, “If the authors made mistakes in names, places, and events, what else did they get wrong? How can the reader rely on anything that appears in ‘Killing Lincoln’”?’
You say the article had no support - how about Edward Steers Jr.? Didn't you read the article???
Can the author of this article give one example from the North and South article? Or is that too much to ask from a Journalist? Yes I did read the post and I also earched the net. The same story is posted everywhere, but I did find one source that stated the Steers' article contains a list of ten errors. It seems you have to subscribe to North and South magazine to read the original article. Steers bases his 10 errors on when BOR ues source material the he does not agree with or considers a secondary source.
So once again a journalist repeats a claim and does not research or find a secondary source. And we wonder how the Media gets away with the Cain harassment coverage... they do it all the time.
