In Harrold, a tiny Texas town, 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. The teachers’ mandate is not only to educate the children, but also protect them. In remote Harrold, the nearest sheriff’s office is 30 minutes away, and people tend to know and trust one another. So the school board voted to let teachers bring guns to school.
