With respect, you’ve clearly not bothered to read the numerous criticisms of how the prosecution case was put together, nor about how chaotic the unit she was in had become.
For a start, the unit was looking after critically ill babies - babies that had problems that fell well outside the unit’s accredited level of competency. They were downgraded to only providing care for fit and healthy babies just after Letby was put on trial, and severely criticised for the conditions on the unit.
Their staffing levels were well below what was mandated for safe working practice, the unit was filthy (including sewage contamination) and the Drs, consultants and many of the nursing staff didn’t have the experience needed to look after babies as sick as the ones in their care.
Letby wasn’t on duty at the times of many of the deaths on the unit, and the main expert witness (who had no recent appropriate experience) changed his determination of the method of ‘murder’ several times to account for gaps that came to light as the case was investigated.
The statistical analysis carried out by the CPS was nonsensical, not least (but not only) because it used incomplete shift pattern data for her. They also discovered that at least one of the key card pads on the unit wasn’t recording entries and exits so the underlying data wasn’t even verifiable.
The method of death that she was supposed to have used has been written off as not credible by many pathologists and experts since the trial. Babies that died and showed the same pathology (but who couldn’t have been murdered by Letby because she was off shift and proven to be elsewhere at the time) were ignored. More than one experienced pathologist examined the ‘murdered’ babies and found no evidence of foul play, yet the chief prosecution expert (the one with no recent clinical experience) found ‘obvious’ evidence of the babies being killed - purely by reading reports.
Recent scandals / cover ups within the NHS as a whole should make you at least a little sceptical - your faith in the NHS not allowing very sick babies to be treated in a district general hospital is touching but, I would suggest, very naive.
If you’re genuinely a paediatric nurse, I’d be making sure you keep your arse covered. Nurses and HCAs are very often the easiest targets when the shit hits the fan.
