HARROLD, Texas — A tiny Texas school district may be the first in the nation to allow teachers and staff to pack guns for protection when classes begin later this month, a newspaper reported. Trustees at the Harrold Independent School District approved a district policy change last October so employees can carry concealed firearms to deter and protect against school shootings, provided the gun-toting teachers follow certain requirements. In order for teachers and staff to carry a pistol, they must have a Texas license to carry a concealed handgun; must be authorized to carry by the district; must receive training in crisis management and hostile situations and have to use ammunition that is designed to minimize the risk of ricochet in school halls. Superintendent David Thweatt said the small community is a 30-minute drive from the sheriff's office, leaving students and teachers without protection. He said the district's lone campus sits 500 feet from heavily trafficked U.S. 287, which could make it a target. "When the federal government started making schools gun-free zones, that's when all of these shootings started. Why would you put it out there that a group of people can't defend themselves? That's like saying 'sic 'em' to a dog," Thweatt said in Friday's online edition of the Fort Worth Star-Telegram. Thweatt said officials researched the policy and considered other options for about a year before approving the policy change. He said the district also has various other security measures in place to prevent a school shooting. "The naysayers think (a shooting) won't happen here. If something were to happen here, I'd much rather be calling a parent to tell them that their child is OK because we were able to protect them," Thweatt said. Texas law outlaws firearms on school campuses "unless pursuant to the written regulations or written authorization of the institution." It was unclear how many of the 50 or so teachers and staff members will be armed this fall because Thweatt did not disclose that information, to keep it from students or potential attackers. Wilbarger County Sheriff Larry Lee was out of the office Thursday and did not immediately return a phone call seeking comment, the newspaper said. Barbara Williams, a spokeswoman for the Texas Association of School Boards, said her organization did not know of another district with such a policy. Ken Trump, a Cleveland-based school security expert who advises districts nationwide, including in Texas, said Harrold is the first district with such a policy. The 110-student district is 150 miles northwest of Fort Worth on the eastern end of Wilbarger County, near the Oklahoma border.
