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.

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.

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.

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 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.

What happened with the opioid epidemic is the Mexican cartels made a very deliberate, corporate decision to undercut the price of opioids. What they discovered was they could increase production, increase potency and decrease the price, and sell it for a third of what the Big Pharma could, or street dealers could, for Big Pharma pills. North America, and to a slightly lesser extent Europe, is being flooded with this Mexican heroin as a direct result of the attempt to undercut American pharmaceutical companies.

I don't recognize myself. I don't know who I am anymore." And it's all fun and games until someone loses an I.
