An armed social studies teacher who fired one shot from a handgun after barricading himself in an empty classroom at a Georgia high school was taken into custody Wednesday, according to police. Officers convinced the teacher to surrender and took him into custody without incident after about 30 to 45 minutes, said Dalton, Ga., police spokesman Bruce Frazier. "We had officers inside the building quickly,” he said. No one was injured aside from a female student who hurt her ankle while rushing to evacuate Dalton High School. The incident occurred two weeks after a school shooting in neighboring Florida left 17 students and faculty dead, renewing the debate about gun control in the U.S. In the wake of that tragedy, President Trump and federal and state legislators have proposed arming teachers, a move backed by the National Rifle Association.
