In the futuristic world of Psycho-Pass, law enforcement is equipped with high-tech firearm, named Dominators. It is able to scan a target's Psycho-Pass and change form according to their Crime Coefficient. It has various modes such as Non-Lethal Paralyzer, which fires non-lethal rounds that immobilizes the target, Lethal-Eliminator which fires a vaporizing shot which cleanly disposes of the target, and Destroy Decomposer that is mainly used against non-organic targets.

Should the target's Crime Coefficient be insufficient for enforcement, the gun will lock itself, preventing it from being fired, even if the enforcement officer's judgement determines otherwise.
