I can understand your view, Naomi, but in reality, how would that work? Only by arresting families after the act, which cannot be in the child's best interests at this point. They were entitled to discharge him from hospital for alternative treatment. The hospital had said they couldn't do any more and obviously the medical profession can and do make mistakes.
According to my sister from FB (not sure how accurate), Ashya was outwardly a happy, smiling child, running around. The tumour was there, but no outward signs. One operation, which caused some brain damage and he could no longer walk, talk or smile. I'm not surprised they lost confidence in them.
