I could probably give you a hlf dozen or more "good" explanations for this, but each would just be specualtion on my part. I believe that there's already been too much speculation in this case - most, or nearly all, of it specualting "bad" explanations - but virtually all without any first hand knowlegde.
Nice try at a dodge, but as I thought, you can't come up with a good explanation.
So, the behavior and actions of Mr. Schiavo are totally independent of the facts of this case, huh? What world do you live in?
