Looking at the damage, obviously the shooter was close to the drone. There are people who fly near other peoples houses. There are people who do not fly near other peoples houses.
The shooter was certainly wrong and even criminal. But I don't even do ordinary landscape photography from locations where someone could step out their door and hit my Canon with their shotgun. They would need a rifle with scope to get me.
The Inspire in particular is a big and loud drone to be flying in a neighborhood for what was probably no reason beyond the pilots amusement.
