Summary
British Columbia has sued OpenAI in California, saying a mass shooting at a school in the province could have been prevented if the company had warned local law enforcement that the shooter had used ChatGPT to plan the massacre. The lawsuit filed in San Francisco federal court on Monday names OpenAI and its CEO, Sam Altman, as defendants. Altman published a letter to the community saying he was “deeply sorry” OpenAI had not contacted law enforcement. The school where the shooting took place is being demolished, and the province has been forced to absorb the costs of a replacement school, mental health care and other effects of the shooting, according to the lawsuit.
