Random person knocking on my door during normal hours gets answered normally. Knocking on doors is high effort enough to filter out most of the spam and my door gets knocked on like twice a year so it's really not a huge loss if I get spammed. Random person knocking at the door at 1am results in me answering the door with one of the USSR's most prolific exports within arms reach in case anybody needs the ol' East Houston treatment. They might be having an emergency and need help but it's also wise to be conscious of who's knocking. If there's three dudes on my porch and a fourth sitting in a running car then I'll ask them what they heck they want without opening the door. I don't answer the door for anyone in a uniform unless I'm expecting them. If the government needs to tell me something or interact with me in any legitimate capacity they'll send a letter.
