Everyone who claims she is innocent doesn’t seem to have a concrete reason for that view
That’s not true. There are quite a few reasons.
When I saw details of the statistical table I immediately thought of previous stats used to convict people like Sally Clark. The table was used by the prosecution and looks damning. But reading the details, it looks a lot like the Texas sharp shooter fallacy. They present a table showing she was present for all the deaths she’s accused of committing. Well of course, they can’t charge her with the other deaths which occurred when she wasn’t there. And there were a larger number of deaths than expected when she wasn’t on duty.
And it’s not just randos on the internet who are worried about how stats are presented. The royal statistical society has written a letter: https://rss.org.uk/news-publication/news-publications/2023/general-news/the-rss-writes-to-the-chair-of-the-lucy-letby-inqu/
The unit was a mess. It had hygiene issues and staffing issues. To give an example, an inquest for a newborn who died in 2014, a year before the deaths for which Letby was charged, found that doctors had inserted a breathing tube into the baby’s esophagus rather than his trachea, ignoring several indications that the tube was misplaced. That’s just one example but plenty of others.
The confession in the diary - when I heard this on the news it was presented as some hidden confession she’d written that had been found, but really she writes contradictory things on the same page. Plus, more importantly it was done as part of therapy. She was told to write down feelings etc.
No pattern to the supposed killings. Normally killers have a method but the deaths don’t have a connection.
A lot of the points supposedly against her on this thread don’t actually show guilt.
