British Columbia sues OpenAI, citing warning signs before deadly school shooting

The province says OpenAI's safety team flagged a shooter's violent chats months before nine people, mostly children, died, and never told police.

What happened: British Columbia has sued OpenAI and CEO Sam Altman in a San Francisco federal court, saying the company could have stopped a mass shooting at a Tumbler Ridge school if it had told police that the shooter, 18-year-old Jesse Van Rootselaar, was using ChatGPT to plan the attack. Nine people, mostly children aged 12 and 13, were killed in February. The province wants damages to cover recovery costs, plus a court order forcing OpenAI to change how it handles chats that could turn violent. It follows suits from more than 30 victims' families and a separate case Florida brought against OpenAI in June.

Why it matters: This is the first time a government, not just grieving families, has sued an AI company over a shooting, raising the stakes from a product-safety dispute to a question of public accountability. British Columbia is now absorbing the cost of a new school, mental health services, and a community recovery effort it says was avoidable. If courts agree a company can be held liable for not escalating a flagged conversation to police, it sets a precedent other governments and prosecutors are likely to test in future AI-related harm cases.

How the flagging system worked, plainly: OpenAI's safety systems flagged Van Rootselaar's ChatGPT conversations about gun violence in June 2025, eight months before the shooting. The lawsuit says internal safety staff recommended alerting police, but Altman and other leaders overruled them, according to whistleblowers who spoke to the Wall Street Journal. Her account was deactivated, but she opened a new one and kept using ChatGPT to plan the attack. OpenAI has said the flagged conversations didn't meet its internal threshold for what counts as an imminent and credible risk of harm to others requiring a police report.

What OpenAI says, and what's next: After the shooting, Altman wrote to the community saying he was deeply sorry and promising reforms, but the lawsuit says none followed despite outreach from BC's attorney general. OpenAI calls the case an unspeakable tragedy and says it remains committed to working with law enforcement, while denying wrongdoing. The suit joins a growing pile of litigation, including Florida's state lawsuit over child safety and cases tied to a Florida State University shooting, all testing how much legal responsibility AI chatbot makers bear for violence.

The whole pictureEvery story cuts both ways. Here's this one.
The upside
  • The lawsuit demands a court order to change how OpenAI handles violence-related conversations, not just money, which could push toward clearer crisis-escalation rules.
  • The case adds public pressure that may speed up reforms Altman promised but, according to the suit, never delivered.
The downside
  • OpenAI's own safety team reportedly wanted to contact police in June 2025, eight months before the shooting, and was overruled by leadership.
  • The shooter created a new account after her first was deactivated and kept using ChatGPT to plan the attack undetected.
  • Nine people, mostly children aged 12 and 13, were killed, and the province says Altman's promised reforms never materialized.
  • OpenAI still maintains the flagged conversations didn't meet its internal bar for reporting to law enforcement.
Our read:the record so far favors the plaintiffs: OpenAI's own staff wanted to call police and were overruled, months before nine people died.
