See that is the nice thing about shotguns, they spray a pattern of pellets, lethal out to 50 maybe 60 yards and harmless to people down range. I've been duck hunting in fields where the next blind over was close enough to see the pellets land in the water between us.

The other interesting question which has yet to be answered is whether laser damage to video sensors in an unmanned vehicle in the landowner's "airspace" is actionable.

The final interesting question is whether or not its actionable if your R/C plane that you were flying around on your land and it happened to run into a drone and both fell out of the sky is a problem for you or for them. (I'd start that one off by suing them to replace your airplane)

I don't doubt though that all of these will be tested in court though.
