Prosecutors used ChatGPT logs in a wildfire trial; jury split 10-2 for defense
Prosecutors in a Los Angeles arson trial related to the Palisades wildfire submitted ChatGPT logs as evidence. The jury was unable to reach a unanimous verdict, ultimately splitting 10-2 in favor of the defense, leading to a mistrial.
Background
A mistrial was declared after prosecutors in a Los Angeles wildfire arson case introduced ChatGPT conversation logs as evidence that the defendant had discussed starting fires with the AI chatbot. The jury deadlocked 10-2 in favor of acquittal. This is one of the earliest known criminal trials where AI chatbot logs (the record of a user's prompts and the AI's replies) were treated as prosecution evidence. Key background: ChatGPT is OpenAI's popular conversational AI; its logs capture the text users type and the AI generates. The case raises novel legal questions about whether chatbot conversations are admissible as statements of intent, and whether defendants understand their chats are being recorded — issues courts have barely begun to address. The Palisades Fire itself was a major 2021 wildfire that burned over 1,200 acres in the Santa Monica Mountains.
