I can't speak for all coroners and medical examiners, but it is our job, as far as I'm concerned. I'm sure Andrew would agree that if we think this is the cause of death, it is our job to put it there.
I'm fortunate enough to work in Alberta justice, which is full of lawyers who are there to defend me if in giving that opinion I undergo civil litigation. Honesty and truthfulness have to be the bottom line with us. If I feel there's enough evidence to say that this is the cause of death, I have to put it there. That's my job.
