I have read the full article and I still think she is most probably guilty given that the complexity of the case cannot be laid bare in 100,000 words let alone 13. A 10 month trial following years of investigations by the police would be far more revealing and the jury overwhelmingly found her guilty. That isn't to say that I trust implicitly the justice system, I just think that we don't have everything that resulted in a conviction to hand. If there is a retrial maybe a different result comes out but that will also be decided by a lengthy and detailed process.
I also think the article is actually quite poor in quality for a few reasons despite its length. Firstly it gives away its sympathies almost immediately when painting her as a sympathetic figure "saved as a baby", "always wanted to work in paediatrics" and the quite bizarre "pretty in an unassuming way" (not direct quotes as I haven't got the article up but it was along those lines). There is no way the writer is going in with a sense of objectivity.
There is also a definitely snobbery about the British healthcare system in there, where it fails though is by presenting the hospital Letby worked at as being singularly awful. The talk of cramped space, outdated machinery & long, stressful working hours isn't unique to the hospital but a symptom of over a decade of underinvestment and neglect that is felt across the NHS. What the article fails to report is the hundreds of other hospitals in the exact same condition that didn't have the string of infant mortality that Countess of Chester suffered. What was singularly bad at that hospital that resulted in the deaths of those babies? The most likely scenario to me is either A. The management made some catastrophic errors (they don't come out of this looking rosey at all) and managed to pin in on one nurse while also convincing the police, judiciary and peers of her guilt or B. Someone was purposefully killing those infants. B seems much more likely in this instance.
I also find the bloodlust in the beginning of this thread really distasteful but that doesn't persuade me of her innocence and a few medical professionals and journalists working from transcripts and incomplete information will not convince me otherwise.
