You mistake my intent. I'm not saying these parents should be using violence, but I am stating that it may be worth considering, and that I would have very likely resorted to calculated violence in order to gain my own child back by this point. I consider means which these parents have obviously ruled out by this point.
And as for facts, we have wildly conflicting opinions from two regularly-reputable sources: Tufts and BCH (who was referred by Tufts). The former diagnosed Mitochondrial Disease, which makes sense given the symptoms we know. The latter diagnosed Somatoform Disorder, which is psychological in nature. If there is a dispute, then why have doctors at Tufts not asserted their opinion more fervently, or reconsidered their diagnoses? Why have the doctors at BCH not considered the possibility that Tufts may be right? Why hasn't a completely external review been done on this case, which has been an international headline? After all, most medical professionals consider alternate opinions a good thing.
You don't need a PhD to understand that something is wrong with the medical system, at least in this particular instance. One or more parties are obviously withholding information, being suppressed, or are lying. The real question is: why?
In the meanwhile, I side with the parents. Yes, I am biased because I am a parent myself.
