The National Post reports in its Wednesday, April 22, edition that Florida's attorney general on Tuesday opened an investigation into Microsoft-backed OpenAI's ChatGPT over whether there was criminal behaviour involving interactions between the artificial intelligence app and a gunman who killed two people and wounded six others last year at Florida State University. An Associated Press dispatch to the Post reports that Attorney General James Uthmeier said that prosecutors had done an initial review of chat logs between ChatGPT and the gunman, Phoenix Ikner, to determine if the AI app aided or abetted the crime. "This criminal investigation will determine whether OpenAI bears criminal responsibility for ChatGPT's actions in the shooting at last year," Uthmeier said. Florida's Office of Statewide Prosecution has subpoenaed OpenAI for records on its policies and training materials related to threats of harm and reporting potential crimes, according to the attorney general's office. OpenAI spokesman Kate Waters called the FSU shooting a tragedy but said the company had no responsibility. The company proactively shared information with law enforcement and continues to co-operate with investigators, she said Tuesday.
