The harm is realized, not just potential, as the threats caused pressure and required police intervention.[AI generated]

Why's our monitor labelling this an incident or hazard?
The AI system (Taipei Metro's AI customer service) was used by the perpetrator to send threatening messages that caused public fear and disrupted the operation and safety of critical infrastructure (the metro system). Although the AI system itself did not malfunction or cause harm, its use directly contributed to the harm by enabling the communication of threats. This fits the definition of an AI Incident because the AI system's use led indirectly to harm to public safety and critical infrastructure management. Therefore, this event is classified as an AI Incident.
