Some families are opposed to organ donations, and if someone fails to opt-out and then dies, the family may be upset when the body is harvested. A recent case in Northern California involved a 13 yr old girl who had an adverse reaction to anesthetic and was declared brain dead. Her parents fought the declaration, and kept the body on life support for five years, despite the State of California declaring her dead. Her organs could have helped dozens of people but the family was opposed.
