In the tiny Texas town of Harrold, children and their parents don't give much thought to safety at the community's lone school — mostly because some of the teachers are carrying concealed weapons.
"We don't have money for a security guard, but this is a better solution," Superintendent David Thweatt said. "A shooter could take out a guard or officer with a visible, holstered weapon, but our teachers have master's degrees, are older and have had extensive training. And their guns are hidden. We can protect our children."
