alt Hacker News>American president can ask many things. Trump could ask an american citizen he wants to enter his property. The citizen can say "Fuck off you fucking moron" and slam the door in Trump's face since it is the citizen's personal property.
I'm sure that's not how it would go.
With a normal President that's how it will go. To this one the law is irrelevant, you need to have some good firepower in your home of course.
