If This Had Been a Real Emergency…
Jingbin Wang was teaching a foreign policy class at North Carolina's Elizabeth City State University when a man entered the classroom and pointed a gun at him. The gunman told him to close the door and ordered seven students to line up along a wall. The man said he had been kicked out of the school and threatened to kill one of the students. After about 10 minutes, campus police rushed in and subdued the man. Only later did Wang and his students learn that it was all just a drill to test the school's preparedness for a real gunman.
