I wrote this on another thread. The Tortoise podcast I refer to is called Lucy Letby Expert Witness. It doesn't explore guilt or innocence instead talks around the role of EW in trials.
In the Tortoise podcast that I linked on the page before Dewi Evans said the following. (It may not be fully correct, but will be 99% correct) (Around about 13 minutes in)
"Babies are simple things, there's not a lot that can go wrong with them. If they are premature, they have breathing difficulties, they are at risk of infection, they are at risk of haemorrhage and of course newborn babies may have congenital problems. That's about it really. so going through a checklist of what can go wrong with a baby doesn't take a lot of time........ Babies don't just go from being nice and stable, not requiring much in the way of additional support to suddenly dropping dead. That just doesn't happen."
The presenter then goes onto say that he could find 10 experts in the next 5 minutes who would say that the picture is more complicated than that and that many of the babies were not well and stable prior to their collapses.
He (in his own words) decided within ten minutes of reviewing the medical notes that [one of the triplets] had suffered intentional harm. If he holds the opinion that babies don't just "suddenly drop dead" then he has already made his mind up and will look for the evidence to prove that.
The issue is bigger that LL's guilt, it is the role of expert witnesses in trials and how you know that they are truly an expert.
(This thread) I believe that some of the verdicts will be ruled unsafe - especially baby C, and the two insulin poisonings (no evidence that it was her other than, she is guilty of X so can also be found guilty of Y)
As for failing a placement, 25 years ago I had an absolutely dreadful clinical placement. The supervisor (imo) was absolutely dreadful and she would set me up to fail (specific tasks) My last supervision session with her was basically a character assassination where she told me I would never amount to anything. Fortunately she did pass me, and I went on to have a brilliant further placement, ironically in the setting she told me I would be hopeless at.
As others have said, too much shouldn't be read into one placement.
