I rationalize out, well, how much help could you really be, you know? And maybe if people saw this, they'd realize the brutality of war and figure out there's got to be some better way than killing human beings who are just trying to farm a field.

Not one Wall Street executive has been charged with crimes since the 2008 financial crash.

The helicopter was a U.S. Navy helicopter. There were no civilian helicopters available to film companies, so they just made some stuff out of two-by-four wood. And I would straddle a two-by-four out from the helicopter with a camera and what we call a high hat, which is a low metal stand.

I was shooting all this time. And there was only one guy who helped to pull him. And I had to think whether I was going to keep shooting or help the guy. And so I kept shooting and then they put him in this little clinic, and I photographed through the window while they had to amputate his leg. And I felt very strange because I didn't - I felt I could have helped, but I didn't help. But then I also felt elated that I was getting a shot that would be important to the film.

That force - which the system tried to laugh at - when it finally broke through and the movement was recognized, the media said they were "just a bunch of spoiled kids, dope smokers [who] don't know what the hell they want." To demean it as something laughable - but that didn't work for very long. It's still an ongoing struggle; they're trying to find out how to fight. It's very exciting times.
