I always have said, you know it's not for me to forgive or to condemn, I'm a filmmaker.

I really believe that the past is beyond our grasp and what is essential about the past is something unspeakable.

I believe every time you film anybody, you create reality with that person - whether it's fiction or nonfiction. If you acknowledge that filming is an occasion where people express things they might not otherwise express, that offers a much more insightful analysis of why documentaries - even of the fly-on-the-wall variety - are powerful. I think that our task as filmmakers is to create the most insightful reality given the most pressing questions.

A podium is something you walk up to, you say what you want to say and when you're finished, you leave.

I've become more forgiving, even though I have no patience at all for denial, justification of wrong, rationalization. I've become virtually a pacifist, so I feel that no atrocity is ever justified. I've become more vigilant about evil. I think I recognize its seeds more quickly. I see its source.

Each and every perpetrator was boastful, usually they would invite me to the places where they killed and I would of course accept those invitations because I could document what happened that way.

We lie to ourselves and try to escape that bitter reality by saying that the world is divided into good guys and bad guys, and that we're the good guys. We condemn people as evil to reassure us that we're not like them. If there's to be any hope of preventing these things from happening again, we have to look at the reality. That any act of evil in our history was committed by human beings like us. That, very often, we're all implicated in it.
