The thought occured to me during my commute home. Some of the most obvious things can be hidden in plain sight. Take for instance the Rathergate memos. The error was in plain sight. I this tape, the English speaker would have attracted the most attention - out of the ordinary - thus garnering most of the attention. The Sahab markings and rest could be cosmetic as the most intense examination would be on who the speaker was and what he is saying. Kind of like a sleight of hand trick too, misdirect one's attention to what you want them to see.
Now the only thing left is how it got into ABC's hands, particuarly in view of the CSM article.
I browsed a bit and didn't see this posted...is Jill's site going away?

I agree with you about this general idea.
This has also been run through the CIA/FBI/whatnot. Any native Arabic speaker (I assume they have one or two on their staff) would be able to pick up grammar mistakes with great ease. I seriously doubt that they would only listen to the tape and ignore the words at the bottom of the screen.
Real or not, I am not sure this tape is significant in any way other than proving the fact that some of the people who hate us are not Arab.
The message is the same, the language is different.
