"Every classroom has been equipped with a five-gallon bucket of river stone," says David Helsel, superintendent of the Blue Mountain School District, in Harrisburg, Pennsylvania. "If an armed intruder attempts to gain entrance into any of our classrooms, they will face a classroom full students armed with rocks and they will be stoned."
"At one time I just had the idea of river stone, they`re the right size for hands, you can throw them very hard and they will create or cause pain, which can distract," said Helsel.
Helsel says teachers, staff and students were given active shooter training through a program known as ALICE which stands for Alert, Lockdown, Inform, Counter, Evacuate and they routinely hold evacuation drills for active shooter simulations.
But if a teacher decides to lockdown a classroom, there are rocks in a five-gallon bucket kept in every classroom closet that students could throw if shooters get inside.
Apparently the school also has an electronic system to lock down the school and they "train kids and talk about barricading the doors," he adds.
