After Hurricane Katrina had passed over southeastern Louisiana in August 2005, many people thought the region had been spared from the most severe damage. But the worst was yet to come: the region's protective levees started to fail, and entire communities were overwhelmed by floodwaters. Thousands had evacuated the region, but others stayed behind to ride out the storm, including the residents and staff of St. Rita's Nursing Home in St. Bernard Parish. The wall of water and its aftermath left 35 of the residents dead, and prompted negligent homicide and other charges against the owners of the nursing home. They faced the possibility of spending the rest of their life in prison. Would and should the owners be held responsible for their decision not to evacuate? Correspondent Harold Dow reports.
