I don't disagree on the difference. The only thing I would add is that this was not limited to CBS. I know ABC and NBC showed it as well. I'm not sure if the cable networks did or not.Here's the difference, then:
A president of the United States, even one as bad as JFK was, is an important historical figure. The general public is going to want to know exactly what happened, and they have a right to know.
This guy on the luge is a nameless athlete to practically everyone, his death has no impact on anyone's life, outside of his personal circle of family and friends, and the only purpose See BS served was their salacious desire to be titillated by someone else's trauma.
Professional news services should not cater to the sense of shadenfrued (sorry, can't spell German, the sense of elation at the discomfiture and bad luck of others) but rather establish a reputation for presenting the essential and relevant facts. See BS hasn't been a professional news orgnanization for decades, not since Walther Cronkite decided to interject his personal views on the Vietnam War.
