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

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.

Making it [police movie] as realistic as possible. I'm honored to be here because it doesn't happen that often from what I hear. They keep people like me away. "Come down and say 'Hello' and get out!"

There's an element of realism to it. I immersed myself more in the subject as a young adult. Then I started to get involved with a lot of people that were involved in it, and they would just bring me along basically. And I learned and decided that my Christian charity, what I wanted to do to serve God's will, was to help people that were ensnared by the demonic.

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.

They [NYPD] tell you how you can act and what you can do your whole entire life. But they always stayed out of it. I did a little here and there for the police department as far as a crime scene that might have occult overtones - they would call me and I'd look into it. But it was usually minor little things.

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.
