If it's over your property, send up your own drone carrying a net attached to a parachute, and drop it on his drone.
Now you have 2 drones.
Wonder how much I can get for “ pneumatic net throwers”.
Throws a bolo type net and balls several hundred feet with repeatable range and accuracy. Not a firearm as per ATF.
A good name for it is “NoDrone”.
I like the way you think.
