What's the Line

between distortion or bias, on the one hand, and legitimate competing interpretations, on the other? Could we now compare this FOX vs. MSNBC clip with PBS, for instance? Is any one of these responses (I hesitate to call them analyses) better than the other? or *truer* than the other? And does any of them serve a public function?

UPDATE: Not quite a parallel clip, but. . . . .
