I think this is one of those issues where the deeper you dig, the murkier it gets - and everyone who has spent a lot of time thinking about these issues.

I don't think that any law enforcement got in trouble for the event in Eugene where police sprayed the tree-sitters who were protesting the cutting of the trees for the parking garage.

There are some audiences who are uncomfortable with the ambiguity, though. They want a film to chew their food for them, they want Hollywood endings that tie everything together in the end and answer all of the questions. They are usually people on one extreme of the political spectrum or other and they haven't been happy because the film is not polemical enough on their side. They aren't usually people who aren't interested in understanding points of view that they disagree with - they just want to attack their opponents - and I'm ok with them not liking the film.

I have wondered if I might be placed on a watch list of some sort by the government, though. I know that the documentary filmmaker Laura Poitras, who is a friend and who has made documentaries about controversial Middle Eastern terrorists has had trouble at customs when she travels internationally - but nothing like that has happened to me.

I love to just listen and watch. I could happily watch a security camera at a store. Often during a day I'll see a guy selling pretzels or an argument that somebody's having on a stoop and I'll think, "Oh I wish I had my camera, I wish I could capture this moment." There's something about people being people and interacting that can be so beautiful when it's framed by a camera. That desire to capture people as they are, and the stubbornness to keep going when they don't necessarily want you to capture them being who they are, are key.

I think if the extremists were happy with my films, I'd start to worry.
