Creative lawyers will be all over this. First you get the officer to testify that AI helped write the report, then you call the AI as a witness. When the judge tosses that, you start issuing subpoenas to everyone you can find at OpenAI and Axon.
As others point out, the actual bodycam footage will be definitively probative for the events it records. But there are plenty of cases where the report itself leads to later actions that may be tortious or criminal, and finding out who's to blame for the exact wording used is highly relevant.
Example: AI incorrectly reports that during A's arrest, A made incriminating allegations about B. Based on the report, the police get a warrant and search B's house. When it turns out B is innocent, B sues the department, and when the report turns up during discovery, we're off to the circus.
