This panel did not sit through the full trial, hear witness testimony, or review non-medical evidence.
The jury in a criminal court, after hearing both sides medical experts, found her guilty beyond reasonable doubt.
This "panels" findings, the scope of which was not clear, will likely form the basis of any appeal if they argue that a miscarriage of justice occurred. Until then she is legally guilty.
On the basis of her being legally guilty, the "thrust" of the recent arrests are that they failed to action on an increase in deaths which could have found the cause earlier.
Deaths have since since dropped back to normal levels, or do you have another theory/cover up that multiple Drs, nurses etc are all in on too?
If an appeal succeeds fair enough. That's what were have a legal system for.
