A Texas town known for allowing teachers to carry concealed weapons on campus may become an example for the nation.

Harrold, Texas' school board has allowed approved teachers to carry weapons at the town's single school since a vote 5 years ago.

The town's sheriff's office is 30 minutes from the school.

To be approved the instructor must have a concealed weapons permit (CHL) and be approved by the school board. Texas law allows guns in schools only when the school has given written authorization.

Since the shooting at an elementary school in Newton, Connecticut, no less than five states have begun to consider laws that allow teachers to carry on campus.

Arizona and some other states already have laws similar to the Texas law.
