Well, actually I look at the book and the movie [Deliver Us From Evil] - the movie isn't about a cop or the Devil, it's about God. There's a spirituality. We have aspects of life we're involved in but we really have no idea about the spiritual battle that rages around us that we are the subject of. The whole matter is the Devil tries to take souls away from God, and God tries to keep them. And that's what this is all about.

I saw a lot of that. It made me uncomfortable. He's been studying me. We don't just sit down and talk, he's actually studying me. It makes me a little uncomfortable being under that microscope. But I think Eric [Bana] immured himself wight he script and is doing what he needed to do

There is a correlation between evil. There is a primary evil that comes directly from the Devil. Even though all evil stems from the Devil, the Devil sometimes interacts with people in the physical world and the spiritual world and sometimes there's just plain evil that people do to one another. And I've seen plenty of that over the course of 20 years.

The NYPD never really had anything to do with it. This is stuff I did on my own time. It just so happened to be that I was a cop for my career. It was my religious belief. The NYPD very wisely stayed away from that. I was grateful that they let me do what I needed to do without getting involved because when you're a cop the NYPD controls you 24/7.

I happened to write a book about the stuff I've been involved in over the years. It just so happened that my profession is that I was a cop in the New York City Police Department. I guess people thought it was pretty interesting to have these two things meshed together. My life is pretty boring, I don't know why they're doing this. It's fun.

According to my religious belief, I'm sorry if you feel like I'm pushing this on you - my religious belief is that you behave the way God wants us to behave. And that's simply love God and love one another. If we did that, there would be no need for any of the other commandments. It would be great. But in the same vein, we would have obtained paradise by that point. And it's tougher to get to paradise by that point.

When I learned to build on my faith, the fear pretty much went away. I'm in a dark basement in a home that's demonically infested - that's not my idea of a fun evening, but again it boils down to your faith. That's your protection. That's the only protection we have.
