It's a bit flippant to call a person dressed as a police officer you don't know an armed stranger, but it's factually true, which contextualizes the decision.

I don't know what you think the upside is of letting someone in a police uniform you don't know to come into your home is, no matter how rosy your view of the police. That does not mean being completely unhelpful. That does not being unfriendly to police officers you know. That does not mean being unwelcome to police officers places that are open to the general public, like your porch, your business, your club's facility, etc. It just means that you keep your private residence private to people you didn't invite in unless legally required not to.
