It couldn't happen here.
When Stephen Delgiadice of Newtown, Conn., was interviewed Friday about the shootings at Sandy Hook Elementary School, he said, "It's alarming, especially in Newtown, Connecticut, which we always thought was the safest place in America."
His 8-year-old daughter was unhurt - 18 other students were killed.
Officials in the Warren County School District are taking no chances. The district has policies in place, has protocols in place.
"People say it can't happen here," Superintendent Brandon Hufnagel said. "It can happen anywhere."
"We just finished rewriting our whole entire critical incident plan," Hufnagel said. "It covers every major emergency."
"We're in the process of continually getting all of our administrators and key staff trained with our critical incident command (procedures)," he said. "We're doing that in conjunction with the various police departments and fire departments."
The district's protocols include how and when to lockdown schools and the procedures for allowing visitors to enter buildings.
"On Monday, we'll be bringing all of the administrators in and reminding them about their due diligence," Hufnagel said. "All the doors are locked; we're not propping doors; we're not buzzing people in without a reason."
As buildings are renovated or built within the district, the public entrance procedures will change. At both Youngsville Elementary Middle School and Warren Area Elementary Center, visitors pass through the outer doors and must be buzzed into the office to gain access to the school. "With construction projects that we have, we're changing the way people can get into the buildings," Hufnagel said.
The district has instituted extensive tours of its buildings for law enforcement officers and firefighters. "Those were put into place to allow law enforcement to get a better idea how our buildings are laid out," Hufnagel said. "Those will be ongoing. It's all part of the critical incident plan."
Hufnagel, who came to WCSD from a position as assistant superintendent of the School District of the City of York, is no stranger to serious violent incidents in schools.
In Red Lion Area School District, a principal acted heroically to thwart an adult with a machete in an elementary school in 2001. A different principal was shot and killed by a student at a middle school in 2003.
"That's a very rural school in York, Pennsylvania," Hufnagel said.
It can happen here. But district officials are working to make sure it won't.
"We're doing the best that we can do to ensure that the kids are as safe as they can be while they're in school," Hufnagel said. "School should be the safest place that kids go."
