This is such a tired argument.
Regardless of the sex, creed, colour or religion of the defendant in this case, the evidence is weak at best and fabricated in some areas at worst.
Many reputable experts in the relevant fields have sounded the alarm at the implausibility of some of the proposed mechanisms of death. There is no precedent for death by NG tube nor research supporting it. Any cursory Google would show you how implausible it would be. The dimensions of the tube would make such an act a long drawn out affair and the idea that it could be accomplished surreptitiously on a busy NICU is very questionable.
The liver injury - done with the force of a car crash yet only detected on post mortem with no other signs? Initially regarded as due to CPR because of where the liver sits anatomically. A neonates liver is between 5 and 7cm. The expert who talked about deserts and things falling from the sky could not describe a coherent mechanism for that injury and actively dodged the question.
Forensically the evidence is abysmal and far more couched in terms of the balance of probabilities rather than beyond reasonable doubt.
Of course professionals are raising the alarm post trial - it brings the expert witness community into severe disrepute yet again. It makes a mockery of the justice system, and effectively paves the way for people to be prosecuted due to precedent and circumstantial evidence in complex medical cases.
The strong echoes of the junk science used in shaken baby cases, metaphyseal fractures cases and statistical misunderstanding that lessons were supposed to be learned about in the last few decades must be sending shudders down the spines of those in both the medical and legal fields.
This case needs urgent review from the ground up, especially as Dewi Evans has actually flip flopped on at least one cause of death post trial. How on earth anyone who looks beyond the hoopla at the evidence can think this was a safe conviction baffles me.
