Yep.

Same thing happens with a lot of elder care and long term mental health facilities.

Whole lot of fraud and abuse, of all kinds.

Whoops!

Lost your certification in one state because you got caught defrauding billing hours as a pharmacist? Move a few states away, your cert/degree still exists, but chances are the revokation won't show up because why do a thorough background check? that revokation/demerit is only specific to that other state... And also just falsify your work history a bit.

With prisons, rather notoriously.... literally no reputable professionals administer most executions.

Because the AMA derides most (all?) methods of them as unethical.

... So by definitiom, you only get unethical people doing the executions, and surprise! they fuck them up all the time.
