An Atlanta News First investigation has uncovered flaws in a weapons detection system currently being used in Atlanta Public Schools (APS) that has also been approved in the DeKalb County School District (DCSD).

The weapons detection system is called Evolv, and is manufactured by Massachusetts-based Evolv Technologies. According to a private report Evolv commissioned and Atlanta News First Investigates obtained, Evolv failed to detect four out of every 10 knives during a 2021 field test at an Ohio sports venue.
