What is the main conflict in Unnatural Death: Confessions of a Medical Examiner by Michael Baden?

In this biography Michael Baden explains the ends and out of a medical examiner. Baden gives the history of ME's dating back to the 1100s when a coroner was not much more than a tax collector. His duties were to investigate suspicious deaths to make sure they were not suicides; if they were, any money would go to the king instead of the deceased person's family members. Baden describes how over time the need to understand how, why, where and when a person died helped the office of coroner to evolve into what is now known as a medical examiner. Even to this day the law varies from state to state on whether or not there is trained medical examiner or coroner in office.
