How about demanding that she at least be offered oral sustenance? Denial of oral sustenance, when such denial would kills someone, is expressly forbidden. Of course, Greer's denial of oral sustenance is supposedly for the purpose of ensuring Terri doesn't get fluid in her lungs and develop pneumonia, but I think Jeb could clearly say that--regardless of what Judge Greer claims--that denial of oral sustenance in this case would have the effect of killing her.
Would you like Jeb to overturn the court order for Terri by executive order? Would you like Jeb sued for failing to protect Terri? I'm just curious as to how far you'd go.
