New house bonus: Ghosts!

A family in Italy is suing the previous owners of their home. Why? Because it has ghosts. Seems to me the only thing they can sue for is the fact that the sellers obviously didn’t own the home in the first place.
I see this kind of thing happen all the time. The ghosts residing there get called “poltergeists” and such over the fact that they don’t like intruders in their home. Where are the ghost police? Where is the Ghost Housing Authority? The humans living there, of course, make this about them. Those people have got nerve. Read about it here, and tell me what you think.
