Know what to do in an emergency — a tornado or an armed person shooting on campus — and if a person or behavior is suspicious, call campus police, Justin Gaines, University of North Georgia’s chief of police, told a small group at the school’s Gainesville campus Wednesday. Gaines presented the details of UNG’s emergency response plan after a brief lockdown on the campus in Oakwood last week. The plan includes medical, weather, train wrecks, hazardous spills and fires in addition to a person shooting on campus.
