Whilst I don't doubt Letby is guilty, I think there are some very interesting aspects to this unique case. Six of the cases had post mortem which found a natural cause, these had to be over turned to present them as unnatural deaths. Contrary to what TV programmes would make you think, post mortem are as dubious as any other process.
however the claims of death by air embolism are novel and somewhat dubious in themselves, they may be correct but the evidence is minimal*. The poorest evidence is the recalled 'mottling' at time of resuscitation. I have been at enough cardiac arrests to know my immediate recall when trying to write up an arrest is vague. Mottled skin is not that unusual in a sick child, would my recall of this years later in one case be reliable? Is mottled skin a real diagnostic feature of air embolism? This is far more debatable than the evidence around shaken baby syndrome.
*I have personal experience of killing by air embolism; many rats and a few rabbits have been killed by me in this way. So I have no doubt this is a rapidly effective and painless way of dispatching small creatures. I have seen one or two adult humans inadvertently die (not at my hands) in this manner.
