Defensive weapons (and in particular stun and tangler weapons) are munitions designed to incapacitate and disorient a person by making him, her, or it unconscious or immobile. For police and security, the preferable way to disable threats is through the use of a nonlethal weapon. Unlike the soldier, the police officer's primary directive is to uphold the law and protect the citizens, whether the citizen is criminal or not. This is the justification for weapons like the stun gun and tangler spray; they immobilize the target without dealing permanent damage.
