British Columbia Sues OpenAI Over School Shooting
British Columbia filed suit against OpenAI and Sam Altman in California court, the first government lawsuit tying an AI company to a mass shooting via failure to alert police.

The Morning Brief Desk · September 22, 2026 · Based on reporting by BBC World
British Columbia has sued OpenAI and CEO Sam Altman in California court over the Tumbler Ridge mass school shooting. The province accuses the company of failing to report the shooter's troubling interactions with ChatGPT to law enforcement. It alleges the attack could have been prevented had OpenAI warned police about the flagged chats.
The suit is the first by a government to tie an AI company to a mass shooting through a failure to alert police. The claim is potentially precedent-setting. It centers on whether OpenAI had a duty to notify authorities about the shooter's flagged conversations. The case lands in the middle of a global debate over AI safety. And it could test U.S. tech companies' duty-to-warn obligations.
