I recently read Five Days at Memorial: Life and Death in a Storm-Ravaged Hospital by Sheri Fink. It reconstructs the horrible conditions faced by the staff of a hospital that became an island during Hurricane Katrina. They had no power and no running water, yet still had to care for 180 patients, many of them critically and/or terminally ill. Temperatures inside reached 110 degrees. What actually happened there is still in dispute–but a doctor and two nurses were arrested for murder of 20 people. The grand jury failed to indict them. Was it murder, mercy killing, or administration of comfort care?
