Like I said, I always believed in the spirit realm. Whether or not I understood it or witnessed it or was involved in it. There wasn't an incident that made be believe it was real, like I said I had an interest in it and as I grew older I realized that there are some people that are doing this for real. That's when I realized this isn't just a Hollywood thing.

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.

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

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.

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 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.

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.
