If I had a billion dollars and had paparazzi chasing me, I would love for them to try this so that I'd get to mount an AA gun on my yacht and shoot them down.
I have an unshakeable imagine of an Englishman in a tweed jacket chomping on a cigar holding a shotgun. "Hunting ducks always struck me as uncivilized. Skeet can't dodge. Drones, though, drones are perfect."
