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 exact incident date, disclosure date and detection method are not stated; the article date is not used as a value. Developer, model, version, harness, tools, autonomy level and root cause are not stated and are left out. The source does not describe an autonomous agent, so agent_involved, failure_class and trigger are left out. The incident class 'other' and the B1 outcome 'failed' are my judgements: the source says employees review alerts before police are sent, yet the clarinet was flagged. The industry 'education' is inferred from 'middle school'. The ZeroEyes statement that it did not think it made an error is omitted. No remediation is reported. Reversibility and financial loss are not stated. Severity 'minor' is my judgement from the single-school lockdown with no third-party data or systems touched.
