It gets worse. Not only did they interview Killian's wife and kid, who strongly suggested he did not write the memo, there's this from the AP:
"Casting further doubt on the memos, The Dallas Morning News said in a report for its Saturday editions that the officer named in a memo as exerting pressure to "sugar coat" Bush's record had left the Texas Air National Guard 1 1/2 years before the memo was dated.
The newspaper said it obtained an order showing that Walter B. Staudt, former commander of the Texas Guard, retired on March 1, 1972. The memo was dated Aug. 18, 1973. A telephone call to Staudt's home Friday night was not answered. "
At this point, firing Rather isn't sufficient. The entire CBS News staff needs to be gutted. It is rotten to the core.
