Jeff Jacoby: The press, in an unsettling firefight of its own - '...The media may not be the most detested institution in America, but it is surely a contender for the title. A Harris poll in March found that only 14 percent of American adults express a ``great deal" of confidence in the press, while 34 percent -- one American in three -- have ``hardly any" confidence in it. The nation's most trusted institution, by contrast, is the military. According to Harris, 47 percent of Americans have a ``great deal" of confidence in the armed forces. Only 14 percent have ``hardly any." No doubt it is just a coincidence that the small fraction of the public that disdains the military is equal to the small fraction that greatly admires the media. But at a time when prominent newspapers are running stories that are apt to get more soldiers killed, I'll bet Sergeant Boggs and Lieutenant Cotton don't think so.'
