School Security Industry Faces Evidence Shortfall
8.0
After a Dec. 13, 2025 shooting at Brown University, a criminologist examines the rapid growth of the US$4 billion school security industry and finds little evidence that AI-assisted surveillance, gunshot-detection systems, drones, or weapons-screening prevent school shootings. Research is sparse due to low incident rates, so most technologies may mitigate incidents rather than prevent them, prompting caution in school procurement.
Key Points
- 1Highlights rapid expansion of the $4 billion school security industry, including AI detection and response drones.
- 2Notes lack of empirical studies and low event rates hinder evaluation of technologies' effectiveness in preventing shootings.
- 3Urges practitioners to prioritize proven procedures like lockdowns and exercise caution spending on unproven technology.
Scoring Rationale
High relevance and credible sources drive score, but limited empirical evidence and low incident rates constrain conclusions.
