I've spent a lot of time in L.A., it's always reminded me a bit of Jo'burg, which is a deeply segregated city. And L.A. is really like an apartheid city white people just don't go to South Central. It's just a different world.

For some reason, politically there's a distinction between cocaine and crack. Cocaine is not a felony conviction because it's used by middle class and wealthy people. Crack, which is used by people in South Central, carries a felony conviction.

I studied law before I became a filmmaker, and I actually have a great belief in the justice system and the rule of law. I think it's the thing that separates us from animals. I really believe in the rule of law because it's an attempt to bring rational accountability to human behavior, which has a great capability of becoming irrational.
