Q: He's harassing you from 800 miles away by air yet he shows up at your work? I'd call the police.

Like I tell people who call to get their phone number changed "my safety concern is if they can't harass you remotely by phone, e-mail, will they show up at your door?"

He's shown up at the door.

Let the professionals take good care of him. or kit and x, kit knows where to hide the body
