Protection against illegal aerial drones

Here is the video showing this drone stunning rifle in action. Good to know there is technology that could distract drones spying on us or holding guns or explosives from its remote control.
The new DroneDefender uses radio pulses to disable a hostile drone within a 400-meter radius. These pulses interrupt the communications system of the drone, making it think it is out of range. The drone’s safety protocols then kick in, forcing it to either hover, return to its point of origin, or descend slowly as it prepares to land. Because the weapon jams communication with the nearby operator, the DroneDefender also can prevent detonation and other remote functions.
