This sums up my feelings on the case perfectly.
Regarding why the defense didn't call their own experts, I remember reading something a while back from a defense lawyer who wrote the most likely reason for this, in their opinion, was Evans' unusual and arguably unethical behaviour as an expert witness.
Typically, when acting as an expert witness, a medical professional will state the most likely cause of death was this, and here are the reasons why. If asked is it possible x,y, or z happened instead, they may answer that it's possible but unlikely. Any decent prosecution lawyer will try to block them from saying that last bit or switch the focus to them admitting there are other possibilities.
Evans didn't do that. He was adamant that the only possible cause of death was air embolism or insulin poisoning. We now know this not to be true, as other, more qualified experts have put forward alternatives that are more plausible than air embolism or insulin poisoning.
It's thought that when a jury doesn't fully understand the evidence they are presented with, they'll defer to the most confident expert, so calling their own expert might have undermined their case if that witness then went on say Evans' version of events was possible but unlikely, so instead they tried to rely on picking holes in the evidence presented by Evans.
I'll try to find the article I read it in and link it if I can, but maybe one of the legal people on here could confirm if this might be the case?
I do wonder why her original team didn't try to contact Shoo Lee if they knew Evans' theory relied on his research.
On jury trials, I have a question. Are jurors able to ask for a second opinion? My immediate reaction when reading Evans' testimony on air embolism was, "huh?" It made no sense to me, and I immediately went off to look for second opinions and research to support or disprove Evans' theory. If I were on a jury, would I have any way of verifying the likelihood of an expert's testimony, or is it a case of taking them at face value?
