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 that almost every scene was an exploration - it was never going to be just what’s on the page. So I know I was very lucky - we all were - to work with a cast of this caliber. These are extremely experienced and intelligent actors, who are also deeply emotional and - as you say - are also engaged in the world.

What is reflected in the way this behavior is happening - in the way that minorities are treated, and the way that the incarceration system works, and the way that even the police are treated, and the way they're paid, and the way they're trained, and the whole educational system.

And with the Occupy Movement, it's really ironic how the police come as representatives and enforcers of the powers that be, even though the people in the Occupy Movement are really on their side - not in terms of their behavior, but in terms of their economic status, in terms of who the police are in society and how much they're paid, and if you boil it down to the economics of it, the police should be out there marching with the Occupy Movement.

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.

Being in the moment with these guys was just a profound experience every day, and when we shoot a movie it's actually a very short process, especially an independent movie like this. It was only thirty five days of shooting.

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.
