Not quite sure it is done like that…
In fact I would doubt it, as it is used to be the case that the organs of executed criminals were used in transplant operations. Why would you do damage to a heart or other vital organ etc…?
This was quite a hot topic in medical circles during the early 90’s as it was seen as ‘organ harvesting’ and so international medical professionals were reluctant to train Taiwanese transplant surgeons overseas.
But I digress. I doubt it would be a bullet through the back.
