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.

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.

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.

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!"

And, for the record, I didn't murder anybody. I want to make that clear. It's entertainment and it brings about the message I believe Scott wants to portray in this movie. There are a few messages in the movie and I'm not going to tell you what they are, but Scott hits the nail on the head with him.

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.
