As a “last resort” against an active shooter, the Blue Mountain School District in Schuylkill County, Penn., equipped each classroom with a five-gallon bucket of rocks, according to The Associated Press.
Superintendent David Helsel says throwing rocks is more effective than just crawling under desks and waiting.
“When will the river stones actually be used? This is a last resort. Throwing river stones or other items will only be used if all other steps have been taken to avoid contact with an intruder,” he added.
The buckets are stored in classroom closets.
