I don't think the panel's conclusion that there was no political agenda at See-BS is credible, but this ain't all bad.
I think they were trying to get around this by citing the "myopic zeal" (which, apparently, is not bias but rather a rush to get a story onto the news... might be credible if that approach also was applied to stories negative to Democrats). In my mind, "myopic zeal" should go right up there with "fake but accurate" in the panetheon of liberal weasel wording.
To show political agenda they would have had to study CBS's pattern of behavior and show that this fit into a clearcut MO. I'm sure that CBS limited the scope of inquiry to the Memogate story (they didn't want to open a Pandora's Box!) and, in isolation, the panel would not be able to credibly claim a political agenda.
