A Kentucky man recently shot down a neighbors $1,800 drone. The homeowner said the drone was hovering over his yard and taking pictures of his daughter, who was in the back yard.
The drone operator sued the home owner and has now moved this case to Federal court. A decision could determine who owns the airspace over your property.
The 'hobby' drone sales are now a multi-billion dollar industry. Law suits are expensive and I suspect that, more than likely, the attorneys for the drone operator will be paid by the industries.
This is a low profile case but the results could be far reaching as to the use of non-commercial airspace vs privacy.
Clandestine pictures of people at private moments are no longer horded by perverts masturbating in their bathrooms - they are now posted on the internet.
