It was the hospital management that contacted police at the consultants' request.
The consultants convinced themselves Letby was guilty. They had received external reports back saying the unit has serious failings. They had received reviews of case notes saying the deaths had natural causes but that failings of care had probably contributed, and that some children would have survived with better care.
They were asked to engage with the process of accepting the findings and developing a safer unit. They refused to accept the findings. They insisted that the deaths must not be natural and that the police must be contacted and asked to investigate Letby specifically, based on their statistical work.
This happened. Letby was found guilty. Now the new panel brings us back full circle. Each death was found to be natural by at least two impartial external experts then, with failings in care. Each death now has two more impartial expert reports, with natural deaths with contributory failings of care.
I am sure the consultants were sincere, and that they were sincerely upset and horrified, but they were wrong to gloss over the failings of their practice and they were wrong when they convinced themselves they couldn't be at fault and it must be Letby.
I hope they will do what Dr Lee recommended: take the new information on board and reflect on the situation. They could do a lot of good by acknowledging they were mistaken.
