British Columbia sued OpenAI and Sam Altman in a San Francisco court. It claims the Tumbler Ridge school shooting could have been prevented. The shooter used ChatGPT to plan the attack. OpenAI’s safety team flagged her conversations but did not alert police. Altman apologised in April and promised reforms but did not act. The province seeks damages for recovery and a court order for changes. Nine people died in the February attack. The shooter killed her mother and stepbrother before targeting the school. She then died by suicide. OpenAI says it notifies police of imminent credible harm risks. The lawsuit follows others from victims’ families in Canada and the US.
