Lethal injection: what does the physicians' non-role portend?

Sunday's NY Times Magazine had an article by Elizabeth Weil on the boomlet of public and official opinion that is starting to cohere against the administration of the death penalty, in states that still have it, by lethal injection. Two articles in the past year by Atul Gawande (one in the New England Journal of Medicine and one in Nature) focus specifically on the role of physicians in such killings and are particularly worth reading.
