History

Historical Context

On April 20 1999, Eric Harris and Dylan Klebold killed 13 students and a teacher at Columbine High School, prompting U.S. schools to add metal detectors, zero-tolerance rules and the Immediate Action Rapid Deployment tactic. Those post-Columbine safeguards form the model for Police Scotland’s 2026 specialist-unit and explosives-dog deployment at Calderglen High School.
