West Midlands Police OP SAVVY Hotspot Policing with PCSO’s Serving our communities, protecting them from harm
Birmingham South Policing Discussion • LPU Demand Mapping process on geographic location • Prevention, Intervention, Harm Reduction • Community engagement, trust and confidence • Resource? Patrols, PCSO • Tasking and direction versus self deployment based on demand • Performance management - impact
EvidenceBased Policing Theory Professor Lawrence Sherman • Of all the ideas in policing, one stands out as the most powerful force for change: police practices should be based on scientific evidence about what works best. • EVIDENCE BASED CRIME PREVENTION – using research to guide practice and evaluate practitioners
BS & Cambridge Methodology • 12 month Pilot - • Focus on deterrable and visible issues: ASB, Criminal Damage, BDH, BOB, Robbery & Theft Person, Vehicle Crime, all theft (inc bilkings.) • 79 eligible hotspots defined as: • Min nos crimes in a hotspot within 12 months = 36 • Max nos crimes in a hotspot within 12 months =150 • Maximum hotspot radius = 150 meters • Buffer zone/catchment area = 100 meters • Minimum distance between epicentres = 500 meters • “crimes” = street crimes, no shopping arcades / schools / hospitals / leisure centres
Hot Spot Patrol • Designated patrol = 3 times in a given late shift • Temporal demand 3pm-10pm • High Demand days Weds – Sat • Control Hotspots = business as usual • Dedicated patrol by PCOSs • 15 Koper minutes of police presence at least twice per day
WMP & Cambridge Methodology Koper curve theory of hot spot policing. This theory proposes the notion that certain specific locations or neighbourhoods can harbour an unequal distribution of crime in comparison to other locations in that same area. Additionally, this theory goes on to explain that police officers who are highly visible in these areas for 12 16 minutes can cause a reduction in crime as well as calls for service (CFS) within that hot spot
BS & Cambridge Concept ‘Placing a PCSO at the epicentre of a hotspot is likely to both deter prospective offenders as well as cool down potentially volatile situations’
PCSO Patrol - Timing Example BREAK 15 MINUTES 17:50-18:05 1.4 miles; 27 minutes start: 15:30-15:45 0.9 miles; 19 minutes 17:00-17:15 Restart 18:35-18:50 0.6 miles; 12 minutes 0.5 miles; 12 minutes 0.6 miles; 12 minutes 16:00-16:15 16:30-16:45
Objectives • Does dedicated focussed patrol……. • Actually occur? • Prevent crime/incidents happening? • Reduce incident demand in designated hotspot areas? • Tell us what doesn’t work? • Utilise staff proportionately and effectively • Improve public trust and confidence? • Develop engagement ? • Embrace Evidence Based Policing to enhance the PCSO portfolio
Tracking OfficersIn 21st century ARLS Data Analysis
Automatic Resource Location System ARLS • GPS-enabled system • “Sits” on Airways Systems • Uses “Point in polygon” analysis • Locates officers everywhere • GPS-ping every 120 seconds
How Data is Captured? • All Officers entering the geo-fenced area • Data captured by Cambridge identifying entry/exit to hotspots • Broken down to PCSOs as per experiment • Contact invested in new software for future analysis
41% diff – PCSOs only 16% diff – all officers
Incidents Between 14th November 2012 and 18th September 2013
Superstore Hotspot • “Capable Guardianship”
Experimental outcomes • Does patrol occur – yes ARLS and geo-fencing data confirms activity • Does patrol work ? Yes if deployment and aims understood • Prevent crime/incidents happening? Yes • Reduce incident demand in designated hotspot areas? Sometimes - Local developing hypothesis as to why • Does experiment tell us why?? Potentially – ‘we’ need to understand tactical options • Utilise PCSOs proportionately and effectively- provide performance framework -Yes • Effect overall approach to managing demand – Yes, contributory to marginal reductions • Improve public trust and confidence? Ongoing • Develop engagement? Ongoing
Future • How long is a hotspot hot for - which will determine how long our patrol strategy in place • Which method works best – time spent vs nos visits • An answer to the hypothesis around displacement • Tactical variations based on geographic location and local knowledge (capable guardianship) • City vs rural deployment principles (Peterborough Experiment) • Future platform for WMP?
