CBS’s investigation into the forged exas Air National Guard documents story has been released (PDF). Producer Mary Mapes has been fired and three others have been asked for the resignation of four others over the Bush Texas Air National memo story.

Mapes is not just some hack: before she became involved in this major journalistic error, she was also a key figure in breaking the most important investigative story of 2004: Mapes was the producer who first got hold of the Abu Ghraib photographs.

The blogosphere would be a very differnet place if the careers of star bloggers were destroyed every time it is shown that they had failed to take due diligence before rushing to post accusations.
