Prosecutors used ChatGPT logs as evidence in the Palisades fire trial

Prosecutors allege Jonathan Rinderknecht set a New Year’s Day 2025 fire that became one of LA’s deadliest wildfires. Alongside iPhone location data, security footage, and witness testimony, they used his ChatGPT logs, including fire-related image prompts and messages about anger and resentment toward the wealthy.

The case shows how conversations with AI assistants may become digital evidence in criminal investigations, similar to search histories or phone records. It also raises fresh questions about user privacy, data retention, and how courts should interpret chatbot interactions that may be emotional, speculative, or performative.
