This technology is ingenious and a peaceful idea to resolve a conflict or just a mistake. All of the drone drivers are not criminals, often they just don't know what they risk when they fly in a restricted area. The " gun " uses the frequencies of the common ISM bands, and isolates the GPS signal, after you take the control of the machine you can make it land. This is smart because if the drone is not destroyed you can check all of the informations inside it ! What do you think about this ? Personally I found the drones are too intrusive and this solution is perfect !
