I took a leave of absence from the internet company where I was working and bought a camera and a copy of Final Cut Pro editing software and made my first feature film, "Street Fight." It followed a crazy, racially charged mayoral election in Newark, NJ in which a young guy named Cory Booker was taking on the political machine of that city. It went on to be nominated for an Oscar and Emmy and was a real example of DIY film-making.

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 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 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 have a point of view on the issues, but it's a complex point of view that really can't be summed up in a sentence or two. I'm not being intentionally vague or mushy, it's just that - in my mind - the real answer is complicated.

It was our goal to dig into the characters and really try to find out why they think the things they think and why they do the things they do - and we got some amazingly candid and revealing interviews - but it's not my job to offer summary judgment on those interpretations.
