The responses are interesting on this thread.
Noone has any claim to knowledge of the medical care of prem-babies in hospital. I also strongly suspect if they did they would not comment as they woudl have to examine the notes before they did. Therefore any comments about the deaths of the babies are not useful.
People have also no idea of how a "guilty" person would act if they were in the situation LL was in. I was implicated in the death of a patient and it was a terrifying and surreal experience. The patient had died about 6 months before so I had to rely on the notes I wrote at the time and I am sure that if there was a video of the interview I had with the investigator there would be a myriad of interpretations. So we can't make a decision about her guilt based on how we would work in those cirucmstances.
This is why I am focused on the enviroment that Lucy was working in. We have a lot of contemporaneous information about what the issues were on the ward. In summary it was deemed to be unfit due to 1) the lack of oversight from the doctors (there was active recuritment for 2 consultants) 2) the high turnover of nursing staff c) The incorrect root cause analysis used for incident investigation.
To me these all seem very significant points as to why the babies were not safe on the ward. It is entirely possible that LL took advantage of a poorly staffed ward in which to commit crimes, but there simply is not enough evidence to demonstrate that the babies were deliberately killed over the risks of very poorly babies on an understaffed ward.
It is important for everyone safety that clinicians are treated fairly including an taking the working environment are taken into account if you are going to accuse someone of murdering babies. If clinicans feel that they are not valued, listened to or given a fair hearing it creates an atmosphere that ultimately put patients at risk.
