No, I'm sure there is no projection going on, since I have never had any concerns about the police in any country I've lived in so far (all in Europe), never had to do with the police except for one case of registering the theft of my bag, and I've never been to the US. As I've said, if the police wants to talk about you or your business or family, then the generally best advice is to get a lawyer. As for other things they want to talk about, that's fine, as long as you bear in mind the following. First, in many countries police has to investigate any suspicion of a criminal offence even if it is unrelated to the initial investigation. In many countries, police has no leeway about that even if they claim the opposite. Second, the police often investigate someone as a mere witness before formally charging the person for a crime, because that's easier to start with.
