The story so far: The wife of a businessman who was killed in a Florida shooting last year has sued OpenAI on behalf of the bereaved family, claiming that the accused gunman used ChatGPT in order to explore far-right ideologies, prepare his weapons, plan out the attack, and research ways to maximise harm. Two mass shootings — one in the U.S. in 2025 and one in Canada in 2026 — have brought to light the use of OpenAI’s technology in public killings.
OpenAI stands accused of failing to inform the police about ChatGPT use by potential mass shooters, with the AI company facing a U.S. criminal investigation as a result of the Florida university shooting. Now, more regulators, digital safety advocates, and affected community members in both countries are flagging the risks of AI-enabled public killings.
