No source states: loss or records, developer and model, agent tool, could do, deployer.

Severity minor: Test: minor, contained to one deployer. The source states a lockdown at one school and no data or systems of third parties touched.

A surveillance system used at Lawton Chiles Middle School in Oviedo, Florida, applies artificial intelligence to school footage to spot potential weapons. According to ZeroEyes, the security company that runs the system and contracts with the school district, the system mistakenly flagged a clarinet as a weapon. The flagged image led officers to search after it appeared to show a gun, and the school went into lockdown. Police swarmed the school and found a student wearing a military costume for a dress-up day holding his clarinet. The system trains employees to look at alerts before police are sent, but the clarinet closely resembled a rifle. The source reports the lockdown and police search as the consequences and states no other harm.
