Omnilert AI gun detection at Nashville's Antioch High fails to spot the gun in a fatal school shooting
Antioch High School's Omnilert AI weapon detection system did not detect the handgun used in the 22 January 2025 cafeteria shooting, in which a 16-year-old student was killed, another student wounded, and the 17-year-old shooter died by suicide. The system activated only later when responding police drew their weapons; the district blamed camera placement and Omnilert said the gun was not visible to the cameras.
