In the meantime, I've been after him to put up a barrier along my house to prevent this from happening again. Incredibly, he's dismissing my concern as "it was just a fluke and won't happen again". I've called all the bureaucratic gods that be in code enforcement, land use and city planning and they all say there's nothing in the books to protect me with a barrier. There are no laws to protect me.
Any intelligent suggestions?
