I honestly think that with robotics (drones included there) becoming a big thing, there should be no exception on laws. SOMEBODY had to instruct that thing in some manner to do what it did, therefore the drone should be considered a version of the owner or operator.

If I was hovering in front of your daughter's face in your fenced back yard, would it be wrong to shoot me?

We haven't quite gotten around to laws on robots yet, but would you want a robotic representation of a human entering your property? It should be the same with any electronic entity.
