Report-supported
BTAC and NTAC publicly describe multidisciplinary, case-specific investigation and management rather than a demographic profile or standard numerical probability of attack. [15][16]
RESEARCH ROUTE 02
Behavioral Threat Assessment and Management
BTAC, NTAC, multidisciplinary teams, structured professional judgment, supportive intervention, and the line where prevention becomes coercive labeling.
DIRECT ANSWER / EVIDENCE BOUNDARY
Route in brief
- Central claim
- Behavioral threat assessment is most defensible when it begins with a concrete concern, investigates context and capability, prioritizes supportive management, continually reassesses necessity, and avoids treating concern categories as probabilities.
- Evidence posture
- The route separates documented operation, official claim, independent evaluation, legal interpretation, unknowns, and conceptual proposals.
- Scope boundary
- Public institutional models and evidence limits; this route does not diagnose individuals or provide a violence-prediction instrument.
DEFINITION / UNIT / CONSEQUENCE
Read the system as a decision architecture
Behavioral threat assessment is most defensible when it begins with a concrete concern, investigates context and capability, prioritizes supportive management, continually reassesses necessity, and avoids treating concern categories as probabilities.
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.
Report-supported
No single behavior predicts targeted violence, and concern categories are not statistical probabilities. [15]
Caution
Rare-event base rates mean that even apparently accurate indicators can generate many false positives when applied broadly. [15][16]
Caution
Vague behavioral categories can become proxies for disability, mental illness, ideology, religion, isolation, anger, or unconventional interests. [15][16]
Cross-report synthesis
The boundary between prevention and pre-crime depends on evidentiary grounding, intervention proportionality, notice, reassessment, retention, support orientation, and meaningful avenues to challenge error. [15][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.
United Kingdom — London
Gangs Violence Matrix
2012–February 2024
Intelligence watchlist ranking named gang nominals using offenses, intelligence, victimization, and association.
- Documented use
- Inclusion affected targeting, stop and search, enforcement, safeguarding, and information sharing.
- Consequence
- Persistent police attention
- Evidence limit
- It was primarily a watchlist rather than machine-learning prediction; governance and disproportionality failures were documented.
- Rights-risk intensity
- Very high
United States — Chicago
Strategic Subject List / CVRM
2012–2019
Models ranking people for future gun-violence involvement, combining victimization and offending risk.
- Documented use
- Selection produced custom notifications, police contact, and intervention priority.
- Consequence
- Persistent police attention
- Evidence limit
- Independent evaluation did not demonstrate violence reduction and documented increased police contacts.
- Rights-risk intensity
- Very high
United States — Los Angeles
LAPD LASER chronic-offender program
2011–2019
Manually administered points and chronic-offender bulletins supported by analytical platforms.
- Documented use
- Bulletins directed officers to locate, contact, investigate, and collect additional information.
- Consequence
- Persistent police attention
- Evidence limit
- Selection, removal, documentation, and causal outcome evidence were weak or inconsistent.
- Rights-risk intensity
- Very high
United States — Pasco County, Florida
Intelligence-Led Policing program
2011–successor practices
Person and youth lists presented as identifying prolific or at-risk people.
- Documented use
- Selected people and families received repeated visits, monitoring, warrant checks, code enforcement, and heightened accountability.
- Consequence
- Persistent police attention
- Evidence limit
- No public evaluation established predictive validity of the original lists; operational attention itself generated confirming records.
- Rights-risk intensity
- Very high
United States and other deployments
PredPol / Geolitica
2011–2024 company closure
Commercial self-exciting place-time forecasting product deployed in multiple cities.
- Documented use
- Generated short-term patrol boxes for selected offenses.
- Consequence
- Planning or resource allocation
- Evidence limit
- Vendor claims and favorable experiments do not establish consistent incremental crime reduction; company operations ended.
- Rights-risk intensity
- Moderate
United States
FBI BTAC / TATM Initiative
2010–present publicly described
National multidisciplinary behavioral threat assessment, consultation, training, and team-building capability.
- Documented use
- Supports case inquiry, investigative strategy, management planning, and reassessment.
- Consequence
- Support, management, or safeguarding
- Evidence limit
- No standard national algorithmic attack-probability formula is publicly documented; effectiveness evidence is constrained by rare events and referred-case selection.
- Rights-risk intensity
- High
United States
Secret Service NTAC
1998–present
Research, guidance, training, and consultation for targeted-violence prevention.
- Documented use
- Promotes multidisciplinary reporting, information gathering, individualized management, and follow-up.
- Consequence
- Support, management, or safeguarding
- Evidence limit
- NTAC rejects a demographic attacker profile; public guidance does not provide a national numerical probability instrument.
- Rights-risk intensity
- High
United States — trained law-enforcement users
NCBIO-25 structured aid
current use reported
Human-administered structured-professional-judgment aid for threat-assessment personnel.
- Documented use
- Organizes investigative inquiry and concern formulation.
- Consequence
- Support, management, or safeguarding
- Evidence limit
- It is not AI, a population-screening instrument, or a validated probability calculator.
- Rights-risk intensity
- High
China — Xinjiang
Integrated Joint Operations Platform (IJOP)
documented 2010s; current configuration unclear
Region-specific platform aggregating records, checkpoints, sensors, household information, and rule-based warnings.
- Documented use
- 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.
- Rights-risk intensity
- Extreme
Australia — New South Wales
Suspect Targeting Management Plan (STMP)
about 2000–December 2023
Long-running preventive-policing program selecting people believed likely to reoffend for individualized management.
- Documented use
- Plans could direct stops, searches, visits, bail checks, monitoring, warnings, arrest, referrals, and coordination.
- Consequence
- Persistent police attention
- Evidence limit
- Oversight found systemic documentation, youth, legality, and disproportionality problems; model and discretion changed over time.
- Rights-risk intensity
- Very high
FAILURE MODES
What can go wrong
- Protected speech or disability can be reframed as dangerousness.
- Teams may confuse a structured checklist with a validated probability model.
- Information sharing can turn a temporary concern into durable suspicion.
SAFEGUARDS
What responsible governance requires
- Require a concrete, articulable concern and individualized context.
- Separate supportive management from coercive intervention and document the legal basis for each action.
- Build scheduled reassessment, closure, retention limits, correction, and appeal.
- Audit disability, race, religion, age, school discipline, and protected-speech effects.
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.
- How often do teams close cases without coercive action, and is closure durable?
- What comparison populations are needed to evaluate indicators and intervention outcomes?
- Which local commercial tools add scoring practices not endorsed by BTAC or NTAC?
