I have been a witness, and these pictures are my testimony. The events I have recorded should not be forgotten and must not be repeated.

Many people in this world do jobs that are dangerous and where their life is at risk and they feel that there is some kind of value to their job I guess that's how I feel about what I do. There is a social function to documentary photography that is very important and it requires people to take risks.

I want my work to become part of our visual history, to enter our collective memory and our collective conscience. I hope it will serve to remind us that history's deepest tragedies concern not the great protagonists who set events in motion but the countless ordinary people who are caught up in those events and torn apart by their remorseless fury. I have been a witness, and these pictures are my testimony. The events I have recorded should not be forgotten and must not be repeated.

If there is something occurring that is so bad that it could be considered a crime against humanity, it has to be transmitted with anguish, with pain, and create an impact in people - upset them, shake them up, wake them out of their everyday routine.

Starvation and disease are the original weapons of mass destruction. When you burn fields and kill animals, people are left vulnerable.

I don't believe there's any such thing as objective reality. It's only reality as we experience it.

The pictures that were coming from Vietnam were showing us what was really happening on the ground level. It was in contradiction to what our political and military leaders were telling us. They were straight forward documentary images. A powerful indictment of the war, of how cruel and unjust it was. When I finally decided what to do with my life, it was to follow in that tradition.
