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.

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've always been curious in why different people believe the things they do and do the things they do - in the different ways that people live.

Most of this film, however, is about interpretation - are these people terrorists or freedom fighters? Are they good or bad? Is cutting timber good or bad? And I don't feel like the answers to those questions are simple, so we don't try to answer them for the audience. I wanted to elicit the strongest - and most heartfelt - arguments from the characters in the film and let those arguments bang up against the strongest arguments of their opponents.

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

Balancing the complex point of view in the edit room was mostly a matter of challenging ourselves to keep digging deeper.
