This is certainly a unique defense.

The debate over protecting America's schools from violence rages on. As thousands took to the streets across the U.S. Saturday for the March for Our Lives demonstration, one Pennsylvania school district feels it has the solution to stop any potential shooting incidents on it's campus: Give the teachers stones and have them throw the stones at the shooter.

Yes.

CNN says that Superintendent David Helsel from the Blue Mountain School District in Schuylkill County has ordered five gallon buckets full of river stones to placed in all classrooms.

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.

WNEP says that Helsel it's all part of his faculty's active shooter training program known, which is called ALICE. ALICE stands for Alert, Lockdown, Inform, Counter, and Evacuate. The Superintendent says the stones are considered a last resort.
