Maybe they did. I haven't read the trial transcripts, have you?
The Schindler "side" is full of propaganda, matters which muddy the water, and perception that is clouded by factors which are not pertinent to the issues at hand.
And the Schiavo side is pure as the driven snow?
The potassium imbalance which brought on the heart arrest and subsequent oxygen depletion to the brain was DUE TO BULIMIA.
It's a matter of medical record and was a part of the trial.
No one is pure as the driven snow except one, Jesus.
So, no the Schiavo side is not pure at all. It's just that he is not evil incarnate as the Schindler side has made him out to be. The Schindlers believed they were doing what was right. But, that doesn't make them right.
