It's funny how sometimes historians sneer at journalists, yet they depend on us in the future for the material that they mine. You realize that some of the stories wouldn't have been told if you hadn't gotten to them. There is that sense of capturing a moment that was just about to go over the horizon.

When I was trained as a journalist, as a race-relations reporter in Nashville covering the end of the civil-rights movement, we were strictly forbidden to use the first-person pronoun.

When I'm writing about complicated subjects, it usually involves a world. It could be the world of Scientology or the world of Al Qaeda, or the world of counter-terrorism.I look for emblematic beasts of burden - what I call "donkeys" - who can carry the reader through this world.
