A large part of the problem here is that whilst his parents are able to speak freely to the media regarding their perception of his condition and current heath, GOSH (quite rightly) are bound by patient confidentiality to say nothing.
This means that apart from information in the public domain (as pertained to the court cases) they are not able to explain, refute or clarify any statements being made my CA or his family.
For example - the fact that he was not being allowed to go home. This was interpreted by some as GOSH holding him hostage. The doctors now saying there is a 10% chance - who are they? What is their specialism? Why is this incorrect? Again GOSH can't refute these claims.
The whole media circus is inherently biased as only one side of the story is being told and what is more, told by people without the specific medical knowledge and who are understandably emotionally compromised by the situation they are facing as parents.
To people saying "we'll send him to the US" GOSH can't allow it for 2 reasons. Firstly they would have to get a court order to do so (which is theoretically possible), however it would ask what new evidence (over that presented in all other proceedings) was available to show why this was in Charlie's best interests now - and there isn't any. The situation has not changed - in fact it is more likely as time continues that his condition has at best stayed the same or at worst declined.
Secondly even if this legal obstacle could be addressed it would set a dangerous and unethical precedent to allow the parents wishes to over-ride the best interests of the child.
It's a terrible situation and I feel very sorry for his family. However as much as I sympathise for their situation, I cannot agree with their ongoing actions and willingness to play this out publicly and especially the drip feeding of "medical" evidence that puts GOSH in a bad light.
