Rep. Peter King (in photo), R-N.Y., needn't wonder whether anybody will notice his Homeland Security Committee hearing today on "The Extent of Radicalization in the American Muslim Community and That Community's Response." Washington Post columnist Ruth Marcus thinks King's inquiry is appropriate and important. "To ignore the religious nature of the terrorist threat is to succumb to politically correct delusion. To ignore the homegrown religious nature of the terrorist threat is to succumb even further," she wrote. But others have a big problem with King's probe. "To focus an investigative spotlight on an entire religious or ethnic community is a violation of everything America is supposed to stand for," wrote New York Times columnist Bob Herbert. He added: "There is nothing wrong with the relentless investigation of terrorism. That's essential. But that is not the same as singling out, stereotyping and harassing an entire community."
