The sad thing is those types ruin the norm. Most Doctors, Nurses, and hospitals are good. You jave your bad apples just as the police departments and any other profession do.
They can ruin the numbers though. Galveston Texas was showing a lot of folks testing positive. A few dieing, a few recovering. This was for weeks on end. Then someone realized their charts were not right and in a couple of days there was a miracle recovery spike on the charts.
