HARROLD, Texas

- In this 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.

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.

"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."

In the aftermath of last week's Connecticut elementary-school shooting, lawmakers in a growing number of states - including Oklahoma, Missouri, Minnesota, South Dakota and Oregon - have said they will consider laws allowing teachers and school administrators to carry firearms at school.

Texas law bans guns in schools unless the school has given written authorization. Arizona and six other states have similar laws with exceptions for people who have licenses to carry concealed weapons.

Harrold's school board voted unanimously in 2007 to allow employees to carry weapons. After obtaining a state concealed-weapons permit, each employee who wants to carry a weapon must be approved by the board based on his or her personality and reaction to a crisis, Thweatt said.

Employees also must undergo training in crisis intervention and hostage situations. And they must use bullets that minimize the risk of ricochet, similar to those carried by air marshals on planes.

The superintendent won't disclose how many of the school's 50 employees carry weapons, saying that revealing that number might jeopardize school security.

The school, about 150 miles northwest of Fort Worth near the Oklahoma border, has 103 students from kindergarten through 12th grade. Most of them rarely think about who is carrying a gun.

Thweatt said other Texas schools allow teachers to carry weapons, but he would not reveal their locations, saying they are afraid of negative publicity.
