At the University of North Carolina, two shootings 30 years apart show how much has changed

Two shootings three decades apart at the University of North Carolina show how much has changed. Some alumni who remember a deadly shooting in 1995 now have children enrolled at their alma mater in Chapel Hill, where an associate professor was shot to death Aug. 28. One graduate who covered the earlier shooting for the school newspaper is now a journalism professor who kept his students safe during last month's lockdown. In some ways, the era of campus shootings has come full circle though there have been vast changes in the way information spreads.
