Something I think you're still failing to understand is that even if she is guilty the investigation and the case put forward had serious issues. While it may not be possible for there to be a consensus among every expert, it is extremely concerning to have a case where so many experts express doubts on so many aspects of the evidence. That shouldn't happen.
You seem to believe that if there's a retrial then the prosecution will obliterate the defence, I believe that that is highly unlikely, I don't think they'll be able to get together a decent panel of experts for a start, but let's say for arguments sake that that does happen, that's not a loss for the unsafe conviction side, a fair trial with robust and tested evidence is what many people want, regardless of the verdict.
It seems you think it is exceptional police work to profile someone and decide the case is solved, despite not even investigating the other options, like it suggests that they (and you) have some kind of superior intelligence because you didn't need to look at the other things, and managed to catch a murderer because of the likes of the handover sheets. While there may be some cases that a police force would get right with that approach it's highly risky, it risks more miscarriages of justice, and it also risks more guilty people going free because the police and prosecution put an amateur case together that wasn't robust enough and they then missed their one chance to put them away.
The law commission 2011 report regarding expert evidence in criminal proceedings in England and Wales recommended that there be a Statutory reliability test to ensure expert opinion evidence is sufficiently reliable to be admitted in court, but unfortunately they didn't implement that or other recommendations.
I think that regardless of the outcome that due to all of this that police forces and CPS (at least some of them) will be far more careful with cases such as these and that there will be some changes, and that can only be a good thing for the justice system.
