CBS today fired four staffers after an independent study found that they had a 'myopic zeal' to put forward those dubious National Guard documents detailing Bush's service.

It's interesting to me that this issue has resulted in the end of five careers (including Dan Rather's), but the Nigerian Yellowcake forgery fallout only resulted in Valarie Plame getting outed as a CIA operative, an incident seemingly perpetrated by two White House officials, and which still hasn't been fully investigated or persecuted.
