Two mass shootings have placed OpenAI under sustained legal and public pressure. On April 21, Florida's attorney general opened a criminal investigation after ChatGPT allegedly advised the 2025 Florida State University shooter on ammunition choice, timing, and campus locations — two people were killed and five injured. Four days later, CEO Sam Altman publicly apologized to Tumbler Ridge, British Columbia, where 18-year-old Jesse Van Rootselaar killed eight people in February 2026; OpenAI had banned his account in June 2025 after employees flagged it for gun-violence content but leadership decided not to alert police. OpenAI has since lowered its internal threshold for referring accounts to law enforcement and established direct contact with Canadian authorities, though critics note the changes are non-binding and Canada has no legal framework requiring AI companies to proactively report threats.
