To me, the real news in this story is contained in this paragraph. Obviously, there is a schism within the FBI on how to pursue the anthrax case. And the new developments are traced to somebody who isn't even assigned to the case -- but evidently disagrees with how it is being conducted.
Odd. I wonder if Barbara Whasserface's source is a member of the official investigative team, so that we have a case of Duelling Leakers.
I don't think Barbara Rosenberg has a source at all.
