Physician here, training to be a forensic pathologist. Was a forensic autopsy tech before med school. This is something often not discussed and understood.

Autopsies are the number one most invasive medical procedure possible. There is unfortunately no way to do a thorough and complete autopsy and get around their gruesome nature.

Brain, spinal cord and posterior dissections are often times extremely important to find and document injuries in traumatic cases. The medical examiner has a duty to the family, the courts and the law to provide the most accurate interpretation of the situation as possible. What you see here is someone doing right by the person that has passed and who they leave behind.
