I have been involved in something in the same category twice now. Both times there was outrage in the local paper (thank goodness it never got to national level) and both times the people who knew what had really happened, were either whistleblowers or involved in the investigation were constrained to keep silent. On one of the cases, the local MP was publicly involved defending the dismissed and disciplined staff and calling what had happened a "cover up" "victimisation" and so on. That one rumbled on and eventually the MP was able to get hold of the investigation paperwork through, IIRC a Freedom of information request. At that point, when, if there had been victimisation and so on, those disciplined or dismissed could have reamed the local NHS organisation good and proper, the MP made a statement in the paper to the effect that the past was the past and no point in re-opening the issue.
I am not saying that this is the same because how could I know.....what I am saying is that in the case I mentioned, the outcry was from people who were local, who knew the area and the people well and who did not believe the outcome of the investigation was fair or valid.....just saying....
