American cops are the ones who are in the emergency rooms. They're the ones who go to the morgues. They're the ones who have to go tell the families that their son is not coming back, their husband, their wife, is not coming home that night. So when we talk about guns and gun violence and police, let's understand that as well. No one wants guns off the streets more than cops because cops are killed by those guns.

I'm a jazz guy and a Bruce Springsteen guy. So I wanted something more current, and edgier, and angrier. So I asked my kid to educate me about hip hop; he has an encyclopedic knowledge of it. And he did so. I found it to be much richer than I would've thought. I think some of the poetry in it is really spectacular. I threw rap into the book. I think I mentioned Kendrick Lamar. I'm really into Tupac these days. I love Nas, N.W.A.

American cops didn't create that atmosphere, they're the ones though who have to live with it on a daily basis. These are generalisations; you can't make generalisations about hundreds of thousands of people. The New York Police Department, for instance, has 38,000 police officers in it. But most cops, when I talk to them, desperately care about the victims of gun violence. They see it, they experience it.

I never think about a movie when I'm writing a book, because I think only two things could happen and both of them are bad. You write a lousy novel and a lousy film.

There are various kinds of savagery: emotional, spiritual, economic, and cultural savagery.

The Americans take a product that literally grows on trees and turn it into a valuable commodity. Without them, cocaine and marijuana would be like oranges, and instead of making billions smuggling it, I’d be making pennies doing stoop labor in some California field, picking it.

That sounds like Anthony Soprano. He has a point. I've said it before: if you're black and you sell dope, you end up in the big house; if you're white and you sell a large amount of dope, you end up visiting the White House. So it's a matter of race and it's a matter of scale, frankly.
