History

Historical Context

After Eric Harris and Dylan Klebold killed 13 students and a teacher at Columbine High School on April 20 1999, schools added metal detectors, ID badges and zero-tolerance rules, yet the “Columbine effect” inspired over 70 copycat attacks by 2025. The March 2024 shooting at St. Louis’s Mark Twain Elementary, committed by a custodian, echoes that insider-perpetrator pattern and drives new mental-health and gun-access reforms.
