How could doctors do harm to their patients? Not every one is as good as you are. Remember there was a nurse up this way who went from hospital to hospital in the North and killed his patients? They didn't figure out that it always happened on his watch for quite a while. I think he killed eleven people before they got to him. Horrible, isn't it?
Yes. While I was in Florida I saw a story on the news about a nurse who had murdered a baby. She was up for parole. They suspected her of having murdered many more on her shift over the years.
