Wesley J. Smith is a lawyer, and I am not. That means that I'm less hesitant than he is about using the word "murder" for various killings of the helpless and vulnerable. (He is careful not to do it if the murder in question was committed under color of legality.) But this time, he's on a roll and has no qualms about the term.
A doctor in the UK, Dr. Howard Martin, was tried years ago for murdering three patients and acquitted. But now he has admitted in an interview that he has indeed deliberately hastened the deaths of patients (beyond those for whom he was tried) using fatal doses of painkillers. He's pretty good at the double-speak, calling this "giving them dignity" and insuring that they could die "free from pain," but he compares his actions to putting down a dog, which he calls taking "positive action to help a patient in a humane way." He admits that in two cases he provided this "help" despite the fact that the patients did not give their request or permission. (There goes choice again.)
A coroner recently found that the drugs the doctor gave in two cases this year were not "clinically justified."
A disciplinary panel has suspended his license after a hearing indicating that he had exploited his position and that his actions were "arrogant and single-minded" as well as "extremely serious and widespread."
It appears that Martin may well not be prosecuted again for additional crimes, despite his recent admissions. He has been investigated in 30 or 40 deaths, and the disciplinary panel concluded that his injections hastened the death of 18 patients. The drug used (or at least one drug used) appears to have been diamorphine, aka heroin.
