Don't tell any authority that you are doing a thing, unless you have a good reason to tell them. It cannot possibly help you, it can only result in them telling

Don't tell any authority that you are doing a thing, unless you have a good reason to tell them. It cannot possibly help you, it can only result in them telling you you can't do the thing any more. And don't talk to police as a suspect. (I'm not sure if the rule still applies if you are the one reporting a crime)
