“Columbine also changed police response to attacks. No more perimeters. A national task force was organized to develop a new plan. In 2003, it released “The Active Shooter Protocol.” The gist was simple: If the shooter seems active, storm the building. Move toward the sound of gunfire. Disregard even victims. There is one objective: Neutralize the shooters. Stop them or kill them.”
― Dave Cullen, Columbine
