Maybe this comes from a rural up-bringing, but one of the top rules on my list is "Don't mess with crazy neighbors with guns". So, he shot down your toy. Don't start an E-mail conversation with him! Don't call the police on him. Next thing you know it'll be your dog instead of your drone, or worse. Just pack up the pieces and be glad it was something replaceable.

I can't believe this guy voluntarily contacted (and then sued) someone who has demonstrated no reservations about shooting his house.
