Schools keep adding safety measures against gun violence. But do they actually work?
In the 20 years since two gunmen opened fire at Columbine High School in a Denver suburb, schools across the country adopted security measures and policies to safeguard students.
Features that were added are increasingly commonplace — school resource officers, metal detectors, door locks, video cameras, and active shooter response plans. It marks a “hardening” of facilities from outside forces.
The problem, a University of Toledo professor concluded, is studies do not support the belief that such large investments make schools safer.
