Those who think art bell is real.
Did you really think any one or any show could reveal anything and get away with it?
The show is just pure entertainment. There is nothing in that show that is top secret. Mix in a lot of info that is already public knowledge that is no threat to government with a lot of fantasy bs. Add to that spradic phone calls from frightened guys who are breathing heavily on the phone and crying because they are frightened. And just as they are about to reveal the secret, phone goes dead. You have the making of a good entertainment that fools stupid people who live in a fantasy world.

Any of you remember David Booth and his fantasy world? How many times was he on art bell playing the game of revealing 3rd secret of fatima? Remember?
It was the same game with father Martin. There is however one reasonable and logical answer for reasoning of his death if he was killed. He was probably killed by a pissed off listener who suddenly woke up and realised he'd been believing a load of lies and bs.
