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.

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 realized that there is something else that is influencing people to behave like that, and that's the taking of the souls away from God. If you get people to sin, they get pushed further away from God and eventually God doesn't really own the soul anymore. The Devil owns the soul and that's where the danger comes in. Because in the end, there's no do-overs.

I've worked with the Warrens. For about 20 years. I was really good friends with Ed. Ed and Lorraine. We went our separate ways, there were a few differences. In their organization, being that they were from Connecticut, I started the New York City chapter of the organization and handled things in New York. But eventually I was out on my own. But I've been friends with them for a long time.

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.

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!"
