In Dave Cullen's own words

Journalist and author Dave Cullen reflects on the legacy of the Columbine High School shooting and how early media myths shaped public understanding.

Uploaded by Education Week, 2024 · Watch on YouTube

Early Columbine coverage created false myths

Cullen explains that pervasive narratives about the Columbine killers being bullied outcasts seeking revenge were completely untrue. He notes that news broadcasts fed leading theories to trapped students watching classroom televisions, who then echoed those narratives back to reporters as contaminated witness testimony.

School shooters plan rather than snap

Cullen dismisses the idea of shooters suddenly snapping, pointing to extensive federal research showing that every attacker planned their actions. He notes that preparations typically stretched over weeks, months, or even up to a full year.

Columbine established modern school security practices

Cullen observes that current students assume standard security measures like mandatory ID badges, visitor sign-in desks, and lockdown drills have always existed. He points out that none of these practices were standard in schools until right after the Columbine shooting.

Assessing threats through repetition and specificity

Cullen advises educators evaluating potential threats to look for repetition over time rather than a single violent essay or project. In the short term, he stresses that specificity—particularly naming an exact date, location, or weapon—indicates an imminent risk.
