Apparantly CBS hadn't even done that.
It was to a Kinko's ~ in Texas.
The implication was profound. Either Mary Mapes was stepping out of her well-equipped editor's office to use a FAX at Kinko's (to cover her own trail?) or someone else had sent the FAX (and a well-known, but otherwise mentally ill, anti-Bush activist lived there).
I wonder why Mary doesn't mention that phone call?
Yah, a crack team at CBS, huh? Mostly crack.
