lots of worse-case-scenario assumptions there. I agree that when a stranger knocks on your door after your home address is posted online, one can assume they are there to, at minimum, attempt to make contact with you to annoy/film you, something like that. But I’d say the minimum is all that can be reasonably assumed by that action, alone. By knocking on your door, a person is attempting to or asking for contact, but that, by itself, does not rise to the level of threatening because they are not trying to FORCE contact with you like they would be if they attempted to force their way into your home (which could and should be reasonably perceived as threatening). Knocking on your door, without any attempt to force entry, is still giving you the option to simply ignore their attempt to make contact. Nick did not have to open the door for her.
