What happened
What happened
An unnamed 22-year-old man assaulted his former father-in-law with a rubber hammer in a parking lot in Ringsted, Denmark.
The perpetrator planned his attack on his victim with the help of an AI chatbot, asking it to research how he could best harm his father-in-law without actually killing him.
To do this, he managed to circumvent the guardrails of the bot by claiming that he was gathering knowledge for use in a book that he wanted to write. AI chatbots usually refuse to advise on criminal acts.
The man pleaded not guilty and said he had acted in self-defence. He was convicted of aggravated assault and sentenced to ten months in prison.
