I've had this happen to me. To get it over with, honestly, just piss him off to the point where he just gets it over with. When he's in the middle of swatting you, explain to your family what is about to happen, then go outside with your family, and wait. They will come and do their normal routine and question you. That way no one is in the house, everyone knows what's going, they will comply, and on so no one will freak-out and get shot or hurt.
Or, an alternative, have him do his thing, call the police and have them, hopefully, arrive before the SWAT team arrives. That way the police already knows the situation and can handle it accordingly when they arrive.
That's what I did, but the funny part was that he never dispatched one. In your case, though, he may because you said he has proof of doing so. It may seem crazy, but sometimes you have to grab the bull by the horns.
