History

Historical Context

On April 20 1999, seniors Eric Harris and Dylan Klebold killed 13 students and a teacher at Columbine High School, sparking nationwide school-security reforms and a “copycat” script cited in dozens of later attacks. The May 11 2026 shooting by former Marine Tyler Brown on Cambridge’s Memorial Drive revived those concerns, illustrating the enduring influence of the Columbine legacy on contemporary gun-violence debates.
