Wouldn't you think cleaning the house is extreme if the package never arrives? They would need a reason for a warrent, If you don't except because the name on package is not yours?
Not really. Would you rather clean house to take a chance?
And a warrant is not necessarily needed to get you. To come in your house, yes, but you don't have to decline the package in order for them to get you. They can leave it at the door. Once you take it inside, boom. That is acceptance. If you walk it to your car in the guise of going back to the P.O. to return it, that is acceptance as well since you have in your possession.
If anyone remembers the old source Elephant from Tampa, they got him by showing up and trying a controlled delivery. He stepped out the house and told them he wasn't expecting anything and that he was refusing it. They said ok, to sign this receipt declining it and they would return it to sender. They put the receipt on top of the pack and handed it to him with a pen (so he could use the pack to bear down on when he signed it) before he even put pen to paper, they laid him out right then.
