Perhaps inadvertently, the text of the Associated Press's earliest video coverage (scroll down the right frame at the link) of Walter Cronkite's death would appear to say a lot about how journalists see themselves -- and it's not as objective communicators of what is occurring in the world:

Cronkite: "Hello, I'm Walter Cronkite."

AP's Diane Kepler, narrator: He was the most trusted man in America.

Cronkite (November 22, 1963): From Dallas, Texas, the flash apparently official. President Kennedy died at 1PM Central Standard Time, 2 o'clock Eastern Standard Time, some 38 minutes ago.

DK: Walter Cronkite, for many the quintessential TV journalist, has died. For most Americans he was the man to turn to on everything from the assassination of President Kennedy to what to think about the war in Vietnam.
