The biggest mess will come when the boy, sadly and seemingly inevitably, succumbs to his illness. Should it happen in palliative care without the US experimental treatment, the medical experts will be pilloried by an overly emotional public, fed by the media. If the court ruling is overturned and he flies to the states for unsuccessful treatment, it'll be surely said that had he got there earlier he'd have lived.
The second scenario is the most worrying as it will lead to both an outcry against the judiciary (at the highest levels) and doctors (again, at the highest levels). Even posing the question of the timeliness of treatment, as the media surely would, is dangerous. The current campaign has seen slogans such as 'Save Charlie Gard' which implies that the hospital and judiciary are willfully withholding treatment that would certainly save him.
The parent's most recent public statement is hitting emotional nerves across the country (and it is heartbreaking), but it dangerously undermines health professionals: "I think parents know when their children are ready to go and they've given up, and Charlie is still fighting."
The sad and simple truth is that parents don't know this with any certainty at all - the health-care professionals have a greater degree of certainty. Charlie's mother said she 'believes' Charlie is not in pain, contrary to what medical professionals are saying. Charlie's 'fighting' is down to machines feeding him and breathing for him. He can't "see, hear, touch, cry or swallow" according to doctors, and has "irrepairable brain damage and suffers fits." His parents refuse this expert opinion and are convinced that Charlie is responding to their voices and touch.
There's no 100% right or wrong answer to this case, it's not black and white as the media portray it, but the balance of the argument must be swayed towards expert opinion. It's very dangerous for us to undermine them.
And the Pope and Donald Trump can both fuck off. Millions of children are dying in the world as a direct result of the actions and inactions of both of these men. Get your own house in order before you start meddling in issues that have nothing to do with you.
