The way I see it; Terri Schiavo was not dying; her family wanted to get her therapy, which was denied. We will never know if she would have responded, but she was never given the chance.
Casey Kasem is in the end stages of his disease, and is dying; if the food and fluids are not being absorbed and making his dying process more uncomfortable, they are thereby serving no useful purpose.
I refuse to second guess his doctors and family; this is not an easy decision.
My only point was this: the law is supposed to be consistent. In the Schiavo case, the court clearly said the spouse has the final call. In fact they really wouldn’t let people argue the medical pros and cons to a great extent. In this case, the kids are being given the final call and the spouse shut out. Where is the consistency?
(And a personal note, if I am given the warning, I would take things into my own hands. The last thing I ever want is to lay in a bed helpless being tended to by who knows what!)
