For the first time since a gunman opened fire in a school cafeteria, students returned to their school in Chardon, Ohio. Hundreds of them marching together flanked by parents and friends. As one student said, “we are too young to handle this alone, so we will go through it together.” And many of them owe their lives to one teacher, the football coach Frank Hall who chased the gunman out of the building. Today he spoke to the families of the three students who died and to everyone rocked by the tragedy.
