“What I really intend to achieve is to be that fly on the wall, and to try and observe as much as I can without affecting what I've seen. I want to get a sense that what I'm seeing in a place would have happened had I not be there. Were I to make myself an important presence, that would be lost. The danger of a certain other kind of reporting is that people give you what they think you are seeking. People know what you want. When I was traveling in Congo and Rwanda and people asked me what I wanted, I would say, "Nothing. I just want to be here." And that immediately disarmed them.”
