Writing reports is hard? Fuck paper work? Policing used to be easier?
Great, the reports are written for you and the paper work is done for you.
You are still fucking liable for their contents, as you are (or should be) for your actions.
Recorded and written reports are the backbone of accountability.
Don't want to get fucked by the legal system because you have neglected your duties? Don't neglect your duties. Do the reporting, do the paper work.
Using LLM in such reports should be equivalent of perjury. Use LLMs to create bullet points, turn that into a draft (or just submit the bullet points, because someone is likely to feed the report back into an LLM to turn it into bullet points).
But know that you are (or should be) accountable for every last word on that report!
