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.
CaRae Reinisch, who lives in the nearby community of Elliott, said she took her children out of a larger school and enrolled them in Harrold two years ago, partly because she felt they would be safer in a building with armed teachers.
"I think it's a great idea for trained teachers to carry weapons," Reinish said. "But I hate that it has come to this."
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 has 103 students from kindergarten through 12th grade. Most of them rarely think about who is carrying a gun.
"This is the first time in a long time that I've thought about it," said Matt Templeton, the principal's 17-year-old son. "And that's because of what happened" in Connecticut.
Opponents insist that having more people armed at a school, especially teachers or administrators who aren't trained to deal with crime on a daily basis, could lead to more injuries and deaths. They point to an August shooting outside the Empire State Building, where police killed a laid-off clothing designer after he fatally shot his former colleague. Nine bystanders were wounded by police gunfire, ricochets and fragments.
