The neurod is a defensive weapon used by police officers that visually resembles a billy club. At a touch, it painlessly disables a person's greater motor functions and forces them prone, unable to move their limbs.
In order to prevent injury, the neurod disables regions of the body in just such a way as to put the victim in a position where they will not hit their head or anything vital on the way down. Indeed, it is more difficult to kill with this weapon than with one's own bare hands, which- combined with its ease of use and portability- has made it the centerpiece of diffusing the rare physical conflict a police officer might encounter.
