"How do you murder someone with no brain function?"
I heard a rabbi explain it like this. "If there is no breath, there is no life" Therefore if one is removed from a respirator and stops breathing then they are dead.
Terri had minimal brain function and not on a respirator otherwise she was very much alive. If the rabbi's statement is correct then starving Terri to death when she could breathe on her own could be described as murder.
What rabbi?
