No it hasn't been done. All you could offer was that they deferred to Dewi Evans, which is exactly what it seems, they only ruled it out because Dewi said so.
How many medical experts saying this was deliberate harm would satisfy you?
They didn't collapse out of nowhere, the medical notes show clear warning signs of deterioration.
They did not, most of them were very much stable before she got near them. Even she said they lost babies unexpectedly. Unless you count her attacking some babies multiple times to make it look like they were deteriorating naturally.
You're not engaging with the evidence, you completely play down the substandard care and up until now I don't think you acknowledged it at all.
Because it's a separate issue to a murderer on the unit and doesn't explain what happened to the babies.
I've said what I wanted them to do. Investigate it properly and thoroughly. Like they were supposed to. They haven't done that. The hospital has gotten away with the substandard care because the collapses and deaths were put on LL.
They investigated and came to the conclusion LL was responsible. You don't like that because you'd rather believe it was poor care even if that's not the truth.
