Columbine

On April 20, 1999, two heavily armed teenage boys entered Columbine High School in Littleton, Colorado, and murdered 12 students and one teacher. The shooting led law enforcement nationwide to reassess response tactics to active shooter events, moving from a strategy of containment to one of Immediate Action Rapid Deployment.

Police1 coverage of the Columbine school shooting includes lessons from a SWAT cop who responded to Columbine, solutions for stopping school massacres and how to form a threat assessment team.
