There are plenty of officials, who don't want their misdeeds, bias', racism/bigotry or just outright ineptitude recorded. In a similar vein, this former retired chief medical examiner (who testified for the defense and suggested the ridiculous carbon monoxide red herring) is now having 17 years of cases he was in charge of reviewed.
Maryland in-custody deaths to be reviewed after former medical examiner testified in Chauvin trial
"The letter to the Maryland attorney general and others came from former Washington, D.C., chief medical examiner Roger A. Mitchell and was signed by over 400 doctors, according to The Sun."
Along with the brave young lady that showed the world Chauvin's actions, recording the trial has also flushed out some of the injustices done in the past and hopefully will lead to them being reduced in the future.
