I'd answer the door all Tactical Fudd - "Hell yes you boys can come on in. I'll take point. Lets do this!!"

But seriously I would let them in to clear the house for my own peace of mind. A few years ago I came home to a burglary. I went to my safe, got my weapon and cleared the house. I've been trained to clear houses in the military but still ok'd the police to do it when they arrived. Democracy didn't fall and the Constitution didn't burn any faster than it already is because of that decision.
