Good aim! The privacy concern with these things is real. The full opportunity is now there to have these fly up to your window and look into your house. Hard pass on drone deliveries.
Drones can also carry weapons, biohazards, waste, endless possibilities of exploitation, imho.

You don’t shoot at things in public, you don’t shoot into the air near populated/occupied areas, and you don’t shoot at things that don’t belong to you or you aren’t licensed to shoot at. Clearly the thing wasn’t anywhere near his property, so he’ll probably get off light considering how reckless and irresponsible this was.
