Rather and Mapes got caught by FR and the blogs before the show was even off the air.
This caused embarassment to the CBS FRAUDcasting network excutives who thought they had better schooled propagandists.
If they had gotten away with it sufficiently long enough to swing the elections away from the Republican victory it was, the executives would have promoted them instead of getting rid of them. They are simply hoping that the FRAUDcasters who remain in the organization are better at distributing the anti-Republican propaganda. They are not attempting to purge the network of the propaganda in favor of unbiased news, just to make the liberal propaganda more effective.
I posted TankerKC's post earlier in the thread (Post 73). As far as I know he was the first to question the authenticity of the memo and why it looked bogus.
