I like how they keep saying it's a Grey area and they don't know who owns the air space. I hope the FAA makes it extremely clear and the guy who blasted the drone gets slapped with a felony charge of shooting at an aircraft.
Not sure about the legalities, but FAA regs clearly state they are in charge 'from the ground up'.
And this is a classic case of drone hater vs drone enthusiast. My question is, if the drone operator was standing on his rooftop holding a video camera, would the neighbor have shot him in the name of privacy?
If your outside, there is NO reasonable expectation of privacy. If you do expect it, you're a fool.
