I can’t believe anyone is even questioning this concept. Of course you do not have to no matter who it is. They have to get a warrant to make you open the door period, no matter who it is or what agency it is.
You have every right to tell them to take a hike and remove themselves from your property. You have a right to have them charged with trespass if they do not leave your property. Call the cops and have them forcibly removed.
you hear a knock at the door. You peek through the window: it’s the cops, and they’re asking you to let them in. You have a right to say no or not say anything if the police ask to come inside of your home or ask to search your home without a search warrant. You are under no obligation to speak to the police or open the door. It is not a crime to keep the door closed.
If I don't have to answer the door if it's the police, I sure as shinola don't have to do it for some AOC-in-training. As Christopher Walken advises us...
