The Predictive Custody Regime

Repeated failures of surveillance technology push society toward accepting pre-emptive detention based on algorithmic risk scores.

Turning Point: In 2031, after a parolee wearing a malfunctioning ankle monitor commits a mass casualty attack in a Seoul subway station, the National Assembly passes the 'Preemptive Public Safety Act' with 87% approval, authorizing indefinite administrative detention for individuals whose composite risk score exceeds a classified threshold.

Why It Starts

A decade of high-profile crimes committed by individuals under electronic surveillance — cut ankle bracelets, spoofed GPS signals, hacked monitoring apps — erodes public faith in technology-mediated supervision. Each failure generates media firestorms and political pressure that ratchets in only one direction: toward containment. Civil liberties organizations fight each escalation, but polling consistently shows supermajority support for preventive measures. The system that emerges is not a sudden authoritarian seizure but a democratic one: citizens vote, repeatedly and enthusiastically, to cage people who have not yet committed crimes. The algorithm becomes the judge that no elected official has to be.

How It Branches

  1. A series of violent crimes by electronically monitored individuals generates sustained media coverage framing surveillance technology as fundamentally unreliable
  2. Victims' advocacy groups successfully lobby for a 'supervision failure' legal category that holds the state liable for crimes committed by inadequately monitored individuals
  3. Facing massive liability exposure, the Justice Ministry commissions a predictive risk scoring system and proposes administrative detention as a cost-effective alternative to universal high-security monitoring
  4. Constitutional challenges fail when the Constitutional Court rules that preventive detention constitutes 'administrative protection' rather than criminal punishment, placing it outside due process requirements

What People Feel

Lee Jun-seo, a 28-year-old man in Incheon who was convicted of assault at age 19 and served his full sentence, opens his front door at 6 AM on a Wednesday in April 2032 to find two officers holding a tablet displaying his risk score: 0.83. They explain, politely, that he is being transferred to a 'protective residential facility' for an indefinite period. He asks what he did. They tell him he hasn't done anything yet.

The Other Side

Predictive detention systems face a fundamental statistical problem: even a highly accurate algorithm produces enormous numbers of false positives when applied to rare events like violent crime. A system with 95% accuracy screening millions of people would detain tens of thousands of innocent individuals for every genuine threat prevented. The political coalition supporting such a system may fracture once its members or their families begin appearing in the detained population.
