I can't truly imagine myself in her position for one moment. But consider my last sentence carefully. "I feel for the utter desperation Mrs. Schindler must have felt.... but that utter desperation was the reason for the very strict limitations, and the reason for the cops."
Read the entirety of my post at 172. You can't distill this situation into soundbite grabbers. It's not that simple.
The reason for those limitations was nothing other than it was ordained that Terri die. I believe she wasn't allowed water out of glass or cloth was because it was felt it might have kept her alive. If I'm wrong, then giving her that comfort would not have disrupted the process in the least.
