I think Dewi Evans was more concerned about winning than anything else. He's said on several occasions that he's won all his cases bar one, and that it still rankled with him that he lost.
I was a bit shocked to learn that expert witnesses can pocket up to £500,000 during a case!!!
This is from Private Eye Part 14 of their Special Report:
multiple “suspicious events” were identified by Evans, but ten that didn’t involve Letby were disregarded. So the claim that “Letby was always on duty” when something suspicious happened was only true because the prosecution made it so.

Evans identified far more events than the ones Letby was prosecuted for, but because she wasn't there the prosecution left them out. Is no one else going to be investigated for them then since they were suspicious? Or are they now viewed as normal deaths since she wasn't in attendance?
