Man of Honour
Note I am not saying she is innocent, but that it's extremely common for people who've been involved, even effectively as a bystander to wonder if they could have done something, anything to stop something from happening. IIRC it's why you have the term "survivors guilt", as people can feel guilt just from surviving when someone else didn't.
*Apparently if someone kills themselves in front of a train it's not at all uncommon for the driver to end up giving up the job, and in some cases commit suicide themselves due to the guilt because despite the fact they did nothing wrong, they were "in control" of the train at the time.
Also note that on her confessions she also confessed that she didn't do it but the Prosecution only wanted to show one side.
She's probably 100% guilty but when I work in the exact same department as Chester where the Lawyer was fobbing off the Clinicians, when my Lawyer and Solicitors come in saying 'There's things that need investigating' then I'd rather side with them.
From what we've heard the Staff Timesheet should not have been used in Court.
Many Staff were left off it and many incidents/deaths were left off it and that's why Letby ended up at every incident.
Again adding all that info still might show it was her but it needs investigating properly.
