Another reason for the cremation is he likely fears that some ass like Randall Terry is going to photograph the body and leak that to the press. I'm sure the Schindlers would find that repulsive as well. Recall, Randall Terry is the jerk who mailed President Clinton a fetus. He's not one for subtlety if it funds his agenda or gets him publicity.
That's what I think. He's been advised it's the best thing to do for everyone involved.
Then he must be psychic. Randall Terry is just recently on the scene but the cremation order was sought and approved on October 2, 2002 two and one-half years ago.
