CNN yesterday endedthe 20-year career of Octavia Nasr, its Atlanta-based Senior Middle East News Editor, because of a now-deleted tweet she wrote on Sunday upon learning of the death of one of the Shiite world's most beloved religious figures: "Sad to hear of the passing of Sayyed Mohammed Hussein Fadlallah . . . . One of Hezbollah's giants I respect a lot." That message spawned an intense fit of protest from Far Rightoutlets, Thought Crime enforcers, and other neoconprecincts, and CNN quickly (and characteristically) capitulated to that pressure by firing her. The network -- which has employed a former AIPAC official, Wolf Blitzer, as its primary news anchor for the last 15 years -- justified its actions by claiming that Nasr's "credibility" had been "compromised." Within this episode lies several important lessons about media "objectivity" and how the scope of permissible views is enforced.
