The involvement of AI in one of Canada's deadliest mass shootings is under scrutiny, as OpenAI admits to banning the suspect Jesse Van Rootselaar's ChatGPT account before the incident. The company chose not to report her activities to law enforcement, prompting demands for stricter safety measures from the Canadian government.

The rampage started in Van Rootselaar's home, claiming the life of her mother, sibling, an educator, and five students, while two others sustained serious injuries. The case raises concerns about the accountability of AI platforms and missed opportunities to prevent this tragedy, especially when police previously removed, but later returned, guns from her home.

Police investigations and court processes are still ongoing. Experts urge for more scrutiny of emerging digital platforms as new public spheres. A previous diagnosis of various mental health conditions and her online interactions, such as the creation of a violent game on Roblox, add layers to this complex case, highlighting privacy and safety concerns.
