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. 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?
In August, Anthropic, the company behind AI chatbot Claude, flagged a user to San Francisco police after discovering conversations allegedly threatening its CEO, Dario Amodei. According to the San Francisco Standard, citing a police report, the user had claimed to possess an AR-15 gun and suggested he had Amodei “in his sights”. However, when contacted by the newspaper, the man said he was joking and had no intention of carrying out any form of violence.
The person was neither charged nor detained, the Standard said. Fazl Barez, a senior researcher at the University of Oxford specialising in AI safety and governance, said current AI models cannot “reliably” determine whether an interaction with an AI chatbot “is purely hypothetical or is likely to lead to harmful behaviour”. From the context, it may be clear that this is simply a fictional narrative.
If the threshold for flagging potentially harmful content is too low, such a writer could be wrongly flagged,” he told Al Jazeera. They might be trying to understand the risks associated with these pathogens and how to mitigate them. Such discussions may be necessary for legitimate research and education.
