The chatbot murder guide: AI’s struggle between privacy, reporting violence

For months before carrying out Canada’s deadliest school shooting in almost four decades, Jesse Van Rootselaar was consulting an unlikely adviser on how to perpetrate mass murder.

“In a hallway, indoors, or a crowded classroom, the 870 [Remington shotgun] is brutal … Close quarters is its playground,” OpenAI’s ChatGPT guided the 18-year-old, according to reports.

On February 10, 2026, Van Rootselaar shot his mother and half-brother at home before going to a school in the small British Columbia town of Tumbler Ridge, where he killed another six people – including five students – before taking his own life.

Earlier this week, on October 14, US authorities charged a Washington State man with allegedly conspiring with Van Rootselaar to plan the attack. But the mass shooting incident has raised questions that go beyond the traditional legal understanding of culpability.

The British Columbia government in September filed a civil lawsuit against OpenAI and its CEO Sam Altman, accusing them of failing to prevent the incident and claiming they were aware of the conversations that turned deadly. Families of the victims also filed separate lawsuits. OpenAI’s leadership issued a public apology for their failure to notify authorities.

The company has not responded to requests from Al Jazeera for its comments on the lawsuits.

But as the case against OpenAI progresses, it has spurred a familiar debate: Where should a line be drawn between reporting potentially dangerous behaviour and protecting an individual’s privacy?

“Forcing companies to implement a surveillance system implicates very serious civil liberties concerns, and that’s probably a bridge too far for me,” Younes added.
