I suggest that that "Ghost" is merely the editing out of a douche bag that walked through their shot.
Remember the movie with Wesley Snipes and Sean Connery with all the Japan conspiracy stuff? They showed how it can be done, but leaves a residual image just like the one above. They did call that a 'ghost' if I remember correctly - but it's a side effect of video editing.
"Have you heard about the appearance of Michael Jackson's ghost during Larry King's broadcast from Neverland last Thursday? Plenty of America's most staggering dipshits saw it, so CNN devoted an entire segment on King's show tonight to solving the mystery."
