Let me put it this way: if this story came from the Washington Post, New York Times or Wall Street Journal it would a) be more measured and b) have a higher standard for making what is a serious accusation.
I am the opposite. I believe blogs more than either of those sites - especially with important issues such as the war (they have each royally screwed up at least once with covering something as important as the war) .
I think he even says he consulted a lawyer. I'm not sure what else you want, short of the feds getting involved..
