DIRECT ANSWER / EVIDENCE BOUNDARY
Route in brief
Central claim
Person-based systems require the highest scrutiny because a designation can travel across encounters and institutions, intensify surveillance, and generate the same administrative data later presented as validation.
Evidence posture
The route separates documented operation, official claim, independent evaluation, legal interpretation, unknowns, and conceptual proposals.
Scope boundary
Comparative program history and governance; it does not reproduce scoring formulas, targeting criteria, or methods for avoiding police attention.
DEFINITION / UNIT / CONSEQUENCE
Read the system as a decision architecture
Person-based systems require the highest scrutiny because a designation can travel across encounters and institutions, intensify surveillance, and generate the same administrative data later presented as validation.
The route treats operational status, technical capability, official description, independent outcome evidence, legal authority, and human consequences as separate fields. None is inferred from the others.
EVIDENCE-QUALIFIED SYNTHESIS
What the retained reports support
The label remains part of the claim. A citation does not convert a caution, interpretation, or conceptual proposal into verified operation.
Independent finding
Chicago’s early SSL pilot increased recorded police contact without demonstrating reduced likelihood of shooting, murder, or related arrest outcomes for selected people. [5][1]
Report-supported
LAPD LASER used chronic-offender bulletins and manually administered points; the designation directed officers whom to notice, locate, investigate, and contact. [5]
Report-supported
Pasco County’s original program connected predicted risk to repeated visits, warrant checks, code enforcement, monitoring, and family pressure. [5][1]
Report-supported
HART predicted two-year reoffending categories for arrested people and influenced eligibility for a deferred-prosecution program, while officers formally retained discretion. [7]
Independent finding
London’s Gangs Violence Matrix and Australia’s STMP show that watchlists or discretionary plans can produce serious consequences even without sophisticated machine learning. [7][8][1]
CONNECTED CASES
Programs that make the distinction concrete
These cards summarize the retained reports. They do not disclose operational criteria, scoring formulas, screening thresholds, or evasion methods.
Person-based risk or prioritizationNamed personEurope
Random-forest model classifying arrested people into two-year reoffending risk categories.
Documented use
Moderate-risk classification informed eligibility for the Checkpoint deferred-prosecution program, with officer discretion.
Consequence
Investigation or referral
Evidence limit
No sufficiently reliable public evidence in the report established continued operation after 2021; postcode variables and label design raised fairness questions.
Generated investigation tasks and flags concerning named people, relationships, places, and behavior.
Consequence
Detention or coercive intervention
Evidence limit
Public evidence is granular about an associated mobile application but not complete server logic, current configuration, thresholds, or all downstream decisions.
Police-generated contacts can become inputs that perpetuate priority status.
Association, victimization, or presence in a report can be misread as offending risk.
Young people and racialized or Indigenous groups can bear disproportionate attention.
SAFEGUARDS
What responsible governance requires
Require notice, documented inclusion criteria, expiration, removal, and meaningful challenge.
Separate victimization risk, offending risk, intelligence relevance, and service need.
Prohibit police contacts generated by the list from automatically validating continued inclusion.
Evaluate legal grounds and outcomes for each downstream intervention, not only the model score.
OPEN QUESTIONS
What the current public record does not settle
Unknown is an evidence state, not an invitation to assume either a safeguard or a hidden capability.
Which successor practices retain the same operational consequences after a program is renamed or ended?
How many listed people were victims, witnesses, or associates rather than suspected offenders?
What independent evidence shows public benefit after accounting for increased police exposure?
