Incident 1375: OpenAI Allegedly Did Not Alert RCMP After ChatGPT Flagged Violent Chats Before British Columbia School Shooting

Responded
Description: After the 02/10/2026 school shooting in Tumbler Ridge, British Columbia, OpenAI said a user later identified as the suspect, Jesse Van Rootselaar, had previously used ChatGPT to describe scenarios involving gun violence. Those chats were reportedly auto-flagged and reviewed and the account was banned, but OpenAI says it did not alert the RCMP because it allegedly did not present a credible, imminent threat; the company reportedly contacted police after the attack.
Editor Notes: Included for the reported AI-mediated flagging and escalation process. Available reporting suggests the suspect's ChatGPT interactions were flagged by automated systems and reviewed by personnel, and that the associated account was later suspended. The same reporting indicates OpenAI did not notify law enforcement at the time, citing its internal threshold for a credible, imminent risk of serious harm.
