Seven families of Tumbler Ridge school shooting victims filed suit in San Francisco federal court on April 29, alleging OpenAI's automated system flagged the shooter's account for "gun violence activity" in June 2025, after which as many as 12 safety team members urged management to notify authorities — a step leadership declined, choosing instead to deactivate the account. The shooter then opened a second account and continued planning conversations with ChatGPT; despite this, OpenAI has characterized its action as a "ban." Lawyers expect damages to exceed $1 billion and chose California to pursue larger awards than Canadian courts permit. The suits follow CEO Sam Altman's public apology last week for not contacting law enforcement, and more than two dozen additional filings are expected in coming weeks.
