I think people will be surprised at some of the things about the shootings by policemen of unarmed African-American men. But I also think it's a balanced view. Balance has become almost a dirty word these days. It seems we're supposed to pick one side or the other. But these issues are extremely complicated. I think people will be surprised at some of that.

I have sat with the mothers who have lost addicted sons. I have sat with families of kids who have been killed in drug-related gang violence. I have been to the prisons. I have seen the effects. At some point in time, I felt I had to do something other than write a novel about it, that I needed to try to make some sort of contribution, at least try to make some sort of difference in the real world.

Shane Salerno and I adapted my book Savages together, and I learned a lot about adaptation. I think it's an extremely difficult thing to do; adaptation might even be more difficult than writing an original screenplay. It's so much a matter of choices, making choices of what to leave in. It was an education.

My grandmother was from Guelph, Ont. I grew up playing ice hockey, I'm a massive fan. A great-uncle who was in the early days of the NHL played for the Chicago Blackhawks.

I was researching some of the modern-day figures that The Sopranos were moulded on. So many iconic Sopranos moments. James Gandolfini and Edie Falco had an incredible scene together in the kitchen of that house that looked like it was about to explode. That was an iconic series that changed the way we did television. It is also an extremely realistic portrayal of the mafia. Much more so than The Godfather. The Godfather, one of the greatest films ever, but let's face it, a romanticized version of the mob.

How much more money do we have to waste, how many more families have to be destroyed, how many more people have to be killed before you summon the courage to tell the truth to the American people?

I have a life, I have a wife. I have an adult son who I'm very close to, and friends. I go hiking almost every day, four to six miles. In the summer, I'm out surfing or swimming. I think that real, human relationships with people mostly balance dark places in my work.
