Perhaps it did, and perhaps they were right to do so. But, for the police to come out and conduct an interrogation of someone being accused of a crime without first advising him of what was about, the police probably violated procedure by not saying he had a right to not answer questions. They had all the info they needed, the car license, the complaint (of what I don’t know as making someone uncomfortable is hardly a crime). Anyway, first advice when confronted by a cop is say your identity and ask what is this about, don’t answer anything till you know what is going on. The cop is not an arbitrator. Two cops coming to visit is a real danger sign.
I advise all to avoid bringing agents of the government into the mix. It’s better to work things out without them, if at all possible.
