On January 7 local time, the police in Las Vegas, USA, announced that in the explosion incident involving a Tesla Cybertruck outside the Trump International Hotel on January 1, the suspect used AI tools, including ChatGPT, to assist in the planning. Las Vegas Sheriff Kevin McMahill stated that the use of generative AI is a 'game changer' and mentioned that the department is sharing information with other law enforcement agencies.
