But you have been arguing two separate points this whole time. In one breath you are saying basically was it even synthetic insulin? And then the next you are saying it is, but could be innocently explained.
The fact that baby F was administered with synthetic insulin is 100 percent indisputable, the unit may have or may not have realised this at the time, there is certainly questions marks around the standard of care at the unit. I think it is a failing that it wasn’t looked into further but this doesn’t change the fact baby F was given synthetic insulin. Many experts have stated this without a doubt now, there is ample of research out there that supports this it isn’t just a theory. This really is how synthetic insulin works, and no alternative explanation has been given, because there really isn’t one. Myers is not disputing it took place just stating letby isn’t culpable.
What is a theory right now is ‘how’ not if. If you want to come to the conclusion that letby is innocent, the only other plausible explanation would be someone on the ward accidentally putting insulin in baby F’s TPN not once but twice. I know which is more likely.
