The EFF's angle is that the police can use an LLM's initial report maliciously to 1) let incriminating inaccuracies generated by the LLM stand or 2) fabricate incriminating inaccuracies. Afterwards, because the LLM generated the initial report, the officer would have plausible deniability to say they themselves didn't intentionally lie, they were just negligent in editing the initial report. So it's about accountability washing.
