This explains how the CDC suggests Diamonds cause of death should have been handled. - does not parallel what has been reported

This lib rag explains how there was a peak in autopsies 50 years ago, the cost, how modern hospitals get paid whether they do or don't do autopsies.
Once Routine, Autopsies Now Scarce At U.S. Hospitals

But I cannot find any numbers, just general statements about how "many" autopsies were performed 50 years ago, 100 years ago or more. We all know that's how they learned anatomy back then, but that does not prove it was widespread and all the time willy nilly when ever they wanted. So go ahead and prove that for us.
Now if the death was suspicious, all bets are off. There will be an autopsy, then and now.

The end.
