The local department could EASILY meet with the public figure and set up a secret code word that meant all clear. And when a swatting came in, call MTG. If she gives the code word, send two men with balls in sport jackets to meet MTG at the door, who is there expecting them as arranged.
Nothing but an idiot charges in like gangbusters every single time. Same way, no changes. It’s also stupid because it makes the cops predictable ... you know, like for an IED.
Yeah, that could be a good way to handle this.
