I think this applies more widely than just doctors. As a pilot, I could design an execution protocol using nitrogen that would be dirt cheap and totally painless. Any other pilot could write the same one. But I wouldn’t do it, not if you paid me a million dollars. There are too many cases of innocent people getting executed, so I want nothing to do with any of it. Our judicial system is good, but it is not good enough to be relied on for taking life. So I would do nothing to help justify or condone or make tolerable the act of executing prisoners.

Also, this execution is a perfect example. Three bullets to the heart should kill someone dead in seconds. But the article mentions him crying out and flexing for the better part of a minute. That makes me think all three executioners missed the heart, perhaps on purpose.
