Speaking as a member of the British National Health Service (in a medical capacity), I must say that this is a tad confusing. Although the family of someone in a persistent vegetative state will certainly be consulted as to their views on "pulling the plug," it is not a decision that is ever made by the family or even the closest next of kin - the medical team, following the Consultant's instructions will make that decision. I personally have been involved in end-of-life care in many cases like these and we have never, ever, allowed families to make these decisions. So why make the injunction to protect the family? They're not the ones ending someone's life. Although I suppose there's enough morons out there that will decide the family must pay for the NHS's actions... But again, I've never seen that happen either.
