I think the Judge is making the mistake of thinking Connie and Chris can still be reached with logic
I'm not sure it is a mistake. As you accurately said CA is part of a vicious circle that is helping paint the parents into a corner.
However if the American scientist meets with GOSH two things could potentially happen.
-He might, in the face of extensive expert opinion, agree that the brain damage is an irreversible issue that his treatment cannot repair.
-He may be asked by the judge to outline for the court what improvements he would expect in real terms. i.e. See/breathe/feel/communicate/move, and to what extent.
CA seems convinced that the brain damage does not exist and the treatment will give Charlie a measurable (in lay man's terms) improved quality of life. As do the parents.
If their own guy, the scientist they have been raving about, turns around and confirms Charlie's brain damage AND lays out that any hoped for improvements are interesting from a scientific perspective, but not exactly a heartwarming resolution from a lay person's perspective ... the vicious circle may start to melt.
Or it could all go "GOSH got to him/.paid him off/.the government threatened to hurl into the Tower of London for life".
I'd certainly expect some of the latter. But do hold out hope for the former.
Actually quite a lot of hope. Apparently he has been named in the American press. Right at the beginning of proceedings it was stated that some information was "commercially sensitive" and having had a poke around on google there are some patent applications for treatments of the kind being discussed. The guy came accross a little cold yesterday, like he saw Charlie more as an interesting test subject rather than a tiny baby. It's possible that he can't afford to taint his future patent and its saleability with a tinge of inhumanity towards helpless babies. Some people (politically or ideologically motivated) will run with that and possible poke a "Mengele!!" style finger at him and his work. The potential PR fall out might be more than a high profile test subject is worth considering the amount of money that may be resting on this project.
Pretty much I think there is every reason to be optimistic that the American scientist is motivated to take as humane a look as possible at the evidence to support Charlie's condition and prognosis and err on the side of caution in terms of what he promises those who are hoping he is the key to saving a baby's life.
I can't climb inside the judge's head and I'm certainly no legal expert, but I think that tiny glossed over detail about "sensitive commercial details" may have helped shape the judge's choices in terms of how he deals with the American scientist. The judge appears to be doing his damndest to put this case to bed for once and for all. And part of that probably is giving the parents and their supporters every chance to look at the reality of what is being offered, rather than a hope infested fantasy. IYSWIM.
