Families of victims in the Tumbler Ridge school shooting have filed lawsuits against OpenAI, accusing the AI giant of negligence. The suits contend that OpenAI possessed internal data from ChatGPT conversations that pointed to a credible threat but did not alert law enforcement in a timely manner.

Plaintiffs allege that OpenAI failed to act on clear warning signs present in the attacker's interactions with its AI. This legal action seeks accountability and damages, pushing for clearer protocols on how AI companies handle potential real-world violence.

OpenAI has stated the user's activity did not meet the threshold for reporting to police. However, the lawsuits argue for a higher standard of care, questioning the company's judgment and oversight mechanisms.
