Same thing happens when the FBI wants to interview you. Show up with an attorney and a voice/video recorder and you will be told it is against the FBI’s policy to allow their interview with you to be recorded. For some reason they almost always lose interest in interviewing you.
In reality, agreeing to a law enforcement official is almost always a bad idea unless you are the victim of a crime. There is no way it can help you unless you get a written agreement for immunity for all crimes related to the interview.
