I think everybody came into it with the understanding that they would go through an experience that is literally not by the book, that is not executing the script and then going home, but living and breathing these characters and being in the moment with each other, and improvising and creating a lot of present-tense intensity between characters.

There's no solutions to prevent corruption because it's the same thing as putting soldiers in an occupation in a foreign territory - there's too much that's gonna go wrong. There's too much human behavior that's going to get in the way. So you're gonna have to start thinking about it in a different direction, and the different direction is: what is wrong with society?

First of all, we occupied Afghanistan and Iraq and I'm not even talking about the past occupation of them, I'm just talking about currently. And we all know that occupations, in military terms, comes down basically to policing, so you have an army basically functioning as a police force in these foreign territories as part of foreign policy. I'm not knocking that down, I'm just observing.

I think that's an incredibly overwhelming reality that is really at the basis of how we're going to deal with this. Looking at the film, people will say, "Oh yeah, you're criticizing the police." I say, "No."

So the only problem that you have is actually switch things in the department, changing things, controlling things, putting it maybe under federal supervision, and if you fix the department, you'll fix the problems - with police corruption, with brutality, with evidence tampering, all those things.

I think the most emotional part in making the movie and discovering the movie - because it was a process of discovering - is all the scenes with the family.

All the scenes that have to do with the fact that, at the end of the day, we're all engaged - hopefully some of us - in certain causes and ideals and certain ways of living, but we're human, and we're making all these mistakes, and we're caught in particular systems - whatever it is - but ultimately, there's a price paid by the people that are closest to you.
