Actually it’s not subjective, there’s statistical analysis exactly for this purpose. Say there are 10 possible nurses a baby could be assigned to, and some number of deaths per year, there’ll be a point where a certain number of deaths for 1 nurse will be so unlikely that you can say with 95%/99% confidence that it’s not random anymore. Here we have not only total deaths up by a huge amount, but all linked to her - if it was random or hospital negligence it would be distributed across various nurses. I think this number of deaths being linked to her must be statistically significant. I guess they’ll get experts in for this.
