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.

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

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.

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.

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

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.
