Journalists are among a select group, along with warriors and executioners who are authorized to do harm. As James Fallows says, a lot of journalists think that isn't so, and that everything will wash out ultimately. But I don't think they are aware of the long-term damage.

If you travel as much as I do - 165,000 miles last year - you exist nowhere. You're always between heaven and earth, you're always arriving in a new place, you're always starting from the beginning - talk about origins - and you don't know quite what's going to unfold. You live in the unexpected and the inexplicable all the time.
