You are disputing points I'm not arguing, there.
Unscientific/ illogical claims made by the prosecution at Lucy Letby's trial - not an exhaustive list:
Death by air through nasogastric tube is a clinically proven method of murder
A very premature infant can't dislodge his own ETT tube
Air embolism can be diagnosed from crying alone, without any disruption to the heart-rate
Venous air embolism will show symptoms of arterial air embolism in localised patches (yes, that's misunderstanding Shoo Lee's paper)
Deaths explained by pathologists should be considered unexplained for the purposes of statistical comparison of postmortem features.
The same stomach Ph can prove that the stomach is or isn't empty (depending what helps your case)
The same stomach x-ray can demonstrate murder or wind (depending what helps your case)
Guessing how much insulin would stick to a giving set is an acceptable way of proving murder
A collapse that was suspicious when we thought Lucy Letby was on shift is innocuous when she isn't
A cry such as a mother hasn't heard before necessarily means deliberate harm, not, for example, internal haemorrhage (implied)
There is no need for prosecution witnesses to investigate the nature of a pathogen they haven't heard of to rule out natural causes of death
If a child hasn't inherited a blood disorder, antibodies passed through the placenta can't affect him (implied)
If medical staff decide to take a child with pneumonia off a ventilator, their decision must have been correct so cannot have contributed to deterioration
If a baby collapses and dies, that is evidence of deliberate harm.
A child can die of venous air embolism, with Lee's sign, hours after the air is injected, having stabilised in the meantime.
You can determine that a nurse's presence at a selected range of events is suspicious without a statistical analysis.
It is late at night, and there are certainly more. But there are some of them.
