While a staggering 48% of public schools now employ armed guards, a growing body of evidence—from the armed officer who did not stop the Parkland shooter to research showing no significant link to reduced fatalities—forces a critical question: are these costly and ubiquitous security measures truly making our students safer?

Adoption and Policy Interpretation
After fifteen years and billions spent turning schools into fortresses, we must confront the grim arithmetic that we've armored nearly every classroom in America yet still haven't solved the simple subtraction of a child from a shooting.
