  • A sharp increase in the number of homicide cases in T&T during the last decade
  • Over 60% attributed to gang-related activity
  • Yet even within high-crime areas, violence in T&T tends to be concentrated in smaller, micro-level crime places – a strong justification for hotspot policing
  • Cambridge University <> TTPS partnership
spatial and temporal concentrations of homicides in t t n 1 662 1 jan 2009 21 jan 2013
Spatial and Temporal Concentrations of Homicides in T&Tn=1,6621 Jan 2009 – 21 Jan 2013
targets and aims
Targets and Aims
  • Reduce Serious Crime by 50% compared to control conditions
  • Use all 3 “Triple Ts” of Evidence Based Policing
    • Targeting the power few
    • Testing the Intervention through rigorous science and
    • Tracking with GPS tracking and effective management (station-level Compstat)
selection of targets
Selection of Targets
  • All Police Station Districts that have eligible hotspots within their geographic boundaries
  • Top percentile that is responsible for most of crime and disorder in Trinidad and Tobago
  • Excluding Laventille
  • Focus heavily on violent crimes (shootings, woundingsand homicides) and overall crime harm index
  • Focus indirectly on all other serious street crimes
  • Increase legitimacy of T&T Police through effective but fair procedures
proposed program

  • Station-Level Compstat Every 14 days

--hearts and minds, targeting predicted crime

  • Hot Spot Patrols Hot Times—primarily in vehicles
  • Patrol Tracking Maps for Compstat Discussion
  • Searches for Guns
  • Roadblocks Stop & Search
process of random assignment
Process of Random Assignment
  • Rank-Order all T&T Stations according to resources available (n of vehicles, manpower, etc.) and n of serious incidents in 12 months (shootings, homicides, woundings)
  • Exclude BessonStreet Police Station--all treatment *
  • Exclude stations with fewer than 5 incidents in 12 months
  • Random assignment of stations across districts

creating 24 pairs

______

* Extreme outlier with 188 incidents; next in rank is Morvant Police Station with 49 incidents

gps tracking
GPS Tracking

  • Hand held GPS trackers
  • Crucial: It will help us measure the link between police presence and crime
  • As crucial: Officers’ safety!
bi weekly station level compstat
Bi-Weekly Station-Level Compstat
  • Common practice in T&T at Division level, but not yet at station level
  • Ongoing feed of data from CAPA
  • Winning the hearts and minds of officers with:
    • Positive and negative reinforcements
    • Quick response to issues: Discussing challenges and obstacles at the tactical level
    • Accountability: ownership of problems at hotspots by designated officers
outcomes
Outcomes
  • N of all crimes
  • N of homicides
  • Tankebe’s legitimacy surveys
