In the wake of a mass school shooting that took the lives of 17 people in Parkland, Florida, Wednesday, Bulloch County Schools officials are reviewing safety measures in the event something similar happens here. The school system has been conducting “intruder drills” for some time now, said Hayley Greene, public relations and marketing specialist for Bulloch County Schools. School leaders and local law enforcement have partnered in planning safety training and setting policies in place for such an event, she said.
