&gt; It&#x27;s your civic duty to answer the door.<p>If and only if I can reasonably expect that the officer at the door is competent and adequately prepared to perform whatever task he is present to perform.<p>If an officer comes to the door, then -effectively- locks me out of my own house for an hour+ because he failed to prepare for the possibility that I would refuse to permit a warrantless search of my property, then his incompetence has done me a serious injury. (<i>Especially</i> if I have an urgent need to urinate!)<p>I am under <i>absolutely</i> no obligation to -as a courtesy- permit the police to waste my time with their incompetence. There is a system that <i>every</i> taxpayer pays for that provides at least a <i>cursory</i> double-check of an officer&#x27;s search plan, and provides <i>written</i> certification that said plan has been approved. If an officer CBA to get such a certification <i>and</i> announce that he has one in his possession when he knocks at my door, I CBA to waste my time while he locks me out of my home for the time it takes him to get the certification that he <i>should</i> have gotten before he ever made the trip to my place.
