What a bizarre and fascinating story.
At Chester, I don't think most of the consultants were independently convinced anyway. There's no evidence - and in fact, in the witness statements there are outright denials - that most were suspicious before Drs Brearey and Jayaram started agitating to have Lucy Letby taken off the unit after the final deaths.
And then there is this email from another consultant, Dr Gibbs, months after that, and a couple of weeks before Dr Jayaram started claiming he might have seen evidence of deliberate harm a year before. The full email wasn't uploaded to the Thirlwall site, but parts of it were:
(24 February 2017)
I said that although we didn't know that Letby had been the cause of unnatural collapses or deaths, we were still worried that this might be the case and that this problem could resurface at any stage in the future - either here or, if Letby moved, in another Trust. So, whilst we don't know if anything unnatural had happened, we felt we had to do everything reasonable to try to find out. Ian assured me that the issues on our NNU had lead to a great deal of soul searching amongst the Executives and that, for months, our neonatal unit has been given priority at each of the weekly Executive meetings.
I also reminded Ian that most of the 'failings' highlighted by the College review (lack of consultant, middle grade, nursing staffing) also applied to most other NNUs and so didn't adequately explain our increased mortality.
Ian went back to the observation he'd made
when we all met prior to the College review, that the workload intensity had increased
significantly on our unit in the past 2 years (prior to the voluntary regrading). Interestingly, without me needing to bring this up again, he said himself that he understood that we were also worried about the sudden, unexpected nature of many of the collapses, but he then added that perhaps when workload is high sometimes early warning indicators aren't spotted and so patients are more likely to then deteriorate, sometimes rapidly.
...I feel that we've probably done all we can and that it's not appropriate to consider whistleblowing to the media or Police particularly since it seems that 'the Trust' has informed the coroner (in fact two coroners), about our 'dark' suspicions and that's almost the same as telling the Police" ... 'We may have to accept that we are probably never going to get a clear answer to the cause of our increased neonatal mortality and non-fatal collapses and insisting on 'pushing things further' isn't likely to provide any better answers (although the coroners or parents might decide to 'take things further' but it's not clear what they could do to clarify the situation). Amongst all of us, Steve might find it the most difficult not to press for further forensic-style investigations (i.e. direct Police involvement), because he's put so much effort into trying to resolve this issue and has been even more frustrated, humiliated and angered (by Ian especially), than the rest of us - not that any of us have found this affair to be anything other than highly distressing."

It's a very interesting snapshot, acknowledging the uncertainty, the anxiety and the emotional investment. I'm sure that the consultants aren't all blameless in this, but I do think the major responsibility lies with the police, who simply failed to investigate their concerns appropriately.
