According to Rob Stein of the Washington (DC, US) Post, the American Board of Anesthesiologists did a really good thing:
A national physicians organization has quietly decided to revoke the certification of any member who participates in executing a prisoner by lethal injection.
The mandate from the American Board of Anesthesiologists reflects its leaders’ belief that “we are healers, not executioners,” board secretary Mark A. Rockoff said. Although the American Medical Association has long opposed doctor involvement, the anesthesiologists’ group is the first to say it will harshly penalize a health-care worker for abetting lethal injections. The loss of certification would prevent an anesthesiologist from working in most hospitals.
