What right? You hardly have it if you are attacked by robbers or murderers – if the cops can punish you for protecting yourself in your own home, how do you hope to establish a right to do it when pestered by someone flying a drone?
Still, if there are no legal means to protect yourself from surveillance, intrusion, and harm that at least clarifies the situation somewhat, what? What?
a. The drone has to start from somewhere, and the programs that control a lot of their flight have provisions to return the thing to the point where it took off from. Whether this is done by memory or GPS I don’t know, but I have seen it in operation and I know it is not dependant upon a lot of light. The drone can pitch off and return in semi-darkness.
There are lights on the drones that are put there to aid the flyer orientate themselves – if they are turned on they can also help the drone-hunter to follow the aircraft back to base. In most cases this will be very close to the pilot flying it.
b. Attacking people is illegal. To do it legally you need to be a member of the Police Service or the armed forces in receipt of a legitimate order through the proper chain of command. Most people will not be in this situation.
Attacking drones is also illegal, but on a lower scale of offence. If you are going to baseball bat something, bat the drone. It’s still wrong, but it’ll play better in front of the magistrate.
c. Attacking the drone while it is in the air over your property is also probably illegal – ( Hell, everything is illegal in Australia ) – but particularly illegal if you discharge a firearm at it. Resist the temptation to loose off with the 12 gauge.
You may reflect, however, that ancient and medieval people shot fowls out of the air by various means long before gunpowder was invented. There are illustrations in textbooks of the methods which they adopted – and in many cases they were quite quiet affairs. I should avoid crossbows for legal reasons.
Side note: the Swiss or French police seem to be training birds of prey to attack drones to protect sensitive installations. They are, of course, free within their own countries to do as they see fit.
d. The drone flies on a radio signal from the controller. Interfere with this signal and the drone reverts to that return-to-base mode.
e. Drone flyers who use them to spy do so for a number of reasons, but the chief one is that they are smartarses. This character trait invariably means that they are also going to give themselves away by bragging locally or by posting their feats on the internet… Capitalise upon this flaw – make careful enquiries and keep diligent watch. You will eventually find them.
Smartarses also offend repeatedly – because it boosts their ego to bully and menace. If you’ve been pestered once, prepare for the next incursion in whatever way you feel best, knowing that your vigilance will be rewarded.
f. Drones do not fly forever. Their propellers break and their batteries lose capacity and their radio systems go out of tune. This will remove some of them from the scene quickly, and the cost of replacement will mean that they do not return. The expensive ones will require repair too, and here is where you enter the system. Make contact with the repair facility and pay for the names and addresses of their clients. Pay well – information is valuable.
