Where this case falls down for me is the lack of forensic examination around the methods she allegedly used.
If you Google the size of an NG tube for neonates, it's tiny. Forcing sufficient volume of food and / or air into a tiny baby to harm themwould have taken considerable time, and given that other staff and parents would have been in and out of the ward, the opportunity would have been limited and fraught with risk. Since the trial doctors in the field have actively questioned this.
A forensic approach should have investigated how long it would have taken, volume of liquid / air required, and whether this has been seen before in any cases causing collapse.
Likewise the liver injury. A neonates liver is typically between 5 and 7 cm in size, and is located near to where two finger CPR is administered. The emotive language describing the force required to cause the damage seen without external evidence is illogical. If it was caused internally, there would have been other damage.
The insulin issue is a whole other can of worms - the test that flagged it is not suitable for forensic use apparently and further tests should have been done but weren't.
If you are ever accused of a crime and can't prove your innocence, because we operate an adversarial system that hinges more on winning or losing than actual truth and justice, wouldn't you want a more thorough appraisal of the evidence, or would you just accept your fate because experts for the prosecution say you're guilty?
This case was very much more slanted towards the balance of probabilities than beyond reasonable doubt and given the parlous state of the COCH as evidenced by emails from atvlwadt one senior clinician to management at the time, I do think a robust re-examination of this case is called for because right now the whole justice system looks like a bit of a laughing stock at best, and engaging in institutional arse covering at worst, at the expense of all involved including the bereaved families.
