I agree (again) with rosequartz.
If Ashya had died during the journey I would have thought that was tragic but I would still have understood why the parents had felt they had no choice but to act as they did. I agree it was not wise for a little boy who had recently undergone brain surgery to be transported across Europe, but I understand why the parents felt they had to take this chance. They were desperate, and terrified - of losing any say in their son's treatment; of him being forced to have treatment that would either kill him or cause major brain damage; of losing the chance for him to have treatment that they felt, rightly or wrongly, might give him the best chance of partial cure or at least quality of life for his remaining months. These parents do not strike me as being in denial, but seem very realistic about the fact that their son has very little time left and a wish to share that time with him.
To turn your question around janea, if the Wardship proceedings had been carried through and the court had ordered Ashya to have chemotherapy and radiotherapy as recommended by the UK doctors, and he had then died, how would the Court have felt? How would his parents have felt? How would those of us who are so sure the agencies involved so far have acted correctly have felt?
As I said before, I have been involved many times in similar scenarios (thankfully not so high profile) and it is only by reflecting afterwards on the actions taken by all the agencies involved that anything can be learned.
