It’s probably no coincidence that the episode after the chief confirms that Makishima is rare but not unique in his ability to confound Sybil, brutal crimes start cropping up that are committed by those with similarly clear Psycho-Passes. Unlike Makishima, they’re wearing helmets, so it much be a question of technology and not genetics.
It’s later determined that the helmets run scans of everyone and copies the lowest Crime Coefficient among them, so as far as any technology with AI is concerned, the one wearing the helmet is a good law-abiding citizen above suspicion, even as he’s shoving scissors or pens into pharmacists or stripping and beating a woman to death with a hammer. The system is being well and truly gamed.
It’s not surprising there’s extant tech that can, if not flummox Sybil, at least deceive her by copying a clear Psycho-Pass. What is truly chilling is how all of the witnesses to these horrible crimes stand there and do nothing, as the helmet-wearer’s associates film it all. Chilling because years of depending on Sybil to maintain peace has rendered the average person incapable of even fathoming what a murder is, let alone do anything to stop it.
While the helmets are yet another tool Makishima uses to enable would-be murderers and thugs, the effect of the crimes being committed on the city are far more than the sum of their parts. In addition to raising the area stress levels, which could render entire neighborhoods latent criminals if kept up, it is a means of planting public doubt in the system; a crack in the dam that could lead to a deluge.
Of course, that’s precisely what Makishima wants: not just to expose Sybil as a sham, but to demonstrate that humanity has been torn from its natural state into a withering limbo of boredom; boredom he’ll cure. And if anyone manages to catch on and try to stop him, so much the better. The status quo is his bane.
Kogami pulls off some nifty detective work here, studying the recorded scans of the crime to determine the Psycho-Pass was coming from someone other than the culprit, and narrowing their search by identifying someone with the motive to harm the victim. Akane’s role here is small, but amusingly consists of literally staying away from the action, lest the perp copy her Psycho-Pass and render the Dominators inert. In this case, having Enforcers who could successfully target and administer justice to “themselves” proved essential.
