Dear ABC News: How Stupid Do You Think We Are?

An ABC News article reports that, "A man describing himself as an American member of al Qaeda says a new wave of terror attacks against the United States could come 'at any moment,' according to a videotape obtained by ABC News."

Note, however, the beginning of the 3rd paragraph:

While CIA officials say they have not been able to authenticate the 75-minute tape...

So CBS News is supposed to authenticate its sources, but ABC News isn't required to do so. Yeah, right.

And the fact that this is coming four days before election day? I'm supposed to believe this is just a coincidence, right?
