Travel Rule #1 – Carry on the clothes you need
3
Why Share Lessons Between US & SA? Democratic governments Regional & global economic powers Committed to rule of law But High levels of violent crime Historic patterns racial conflict & injustice that complicate policing & justice system processes
4
The Promise Within U.S., evidence has accumulated over the last 15 years that can significantly reduce the most serious gun violence
5
Reducing Homicide Risk (Indianapolis) Note: Each trend is population specific for each graph presented above
6
Plan Briefly review this research evidence Present evidence from Project Safe Neighborhoods Discuss both the process (how) and the substance (why) of these violence reduction interventions Consider implementation issues - how to make it happen
7
Evidence-Based Strategies for Reducing Gun Crime Circa 1994
8
Promising Practices for Reducing Gun Crime, Circa 1999 Directed Police Patrol Project ExileStrategic Problem Solving – Boston Ceasefire Model Kansas CityRichmond Boston Indianapolis PittsburghLos Angeles
9
Key Ingredients Use of analysis to understand & guide interventions Focused on specific problems (gun violence, high risk people, places, contexts) Focused deterrence –Focus on high risk individuals, groups, contexts –Risk communication strategy Steps to increase legitimacy, perceptions of fairness
10
National Academy of Sciences “There is strong research evidence that the more focused and specific the strategies of the police, the more they are tailored to the problems they seek to address, the more effective the police will be in controlling crime and disorder.” National Academy of Sciences, Fairness & Effectiveness in Policing (2004: p. 5)
11
Project Safe Neighborhoods National program to reduce gun crime (2001-2010) Built on these promising practices National program coordinated locally through U.S. Attorneys Offices (94 cover the U.S.)
12
PSN – Federal Program Adapted to Local Context Federal government will provide resources to local initiatives with following conditions: Must be focused on violent crime & homicide Must include a research & analysis component Must include partnerships beyond police & prosecutors
13
PSN Builds Upon Compstat Directed Patrol Focused Gun Crime Project Exile (Richmond) Boston Gun Project (Ceasefire) Strategic Approaches to Community Safety Initiative (SACSI)
14
Foundations PSN Some element of research & crime analysis – adapt national program to local context Focus resources on people, places, contexts driving crime Attempt to increase credibility deterrence Enforcement coupled with social support (prevention & intervention)
15
National Academy of Sciences “There is strong research evidence that the more focused and specific the strategies of the police, the more they are tailored to the problems they seek to address, the more effective the police will be in controlling crime and disorder.” National Academy of Sciences, Fairness & Effectiveness in Policing (2004: p. 5)
16
PSN Key components: Research-based problem solving Focused deterrence Communication of deterrence message Social support for at-risk individuals
17
PSN Evaluation Challenges National, “full coverage,” program Uneven implementation Larger cities offer treatment and comparison sites but may have both citywide and targeted program components Smaller and medium cities – may be no logical comparison site Lack of consistent measures of gun crime across jurisdictions Variation in data availability (e.g., NIBRS vs. non-NIBRS)
18
PSN Impact – Stage One Series of site specific case studies Ten tests of impact on gun crime Reductions in gun crime in all ten sites (impact in two of these studies was equivocal)
19
Summary of Case Studies Project Exile Montgomery Mobile Strategic Problem Solving Lowell Omaha Greensboro Winston-Salem Chicago (Papachristos et al.) Stockton (Braga) St. Louis (significant but also drop in comparison sites) Raleigh (reduction but not significant)
20
Summary of Case Studies Sites chosen because of evidence that PSN was implemented in rigorous fashion Thus, not generalizable but suggest that PSN may have an impact where effectively implemented
21
PSN Impact – Stage Two Assess impact of PSN in all U.S. cities with populations of 100,000+ Trend in violent crime 2000-01 compared to 2002-06 Compare PSN target cities with non-target cities Compare cities by level of PSN implementation dosage (range 3-9)
22
Measuring Implementation Implementation Dosage –Research integration –Extent & quality partnerships –Federal prosecution for gun crime
23
Overall Finding PSN target cities in high implementation districts experienced significant declines in violent crime in comparison to cities in low implementation districts and non-target cities
24
Violent Crime Trends in PSN Target Cities by Level Federal Prosecution High Prosecution
25
Violent Crime Trends in Non-PSN Sites by Level Federal Prosecution
26
PSN Impact Level of PSN Dosage PSN Target Cities Non-target Cities Low -5.3%+7.8% Medium -3.1%<-1.0% High -13.1%-4.9% -8.89%-0.25%
27
PSN Impact Level of PSN Dosage PSN Target Cities Non-target Cities Low -5.3%+7.8% Medium -3.1%<-1.0% High -13.1%-4.9% Total -8.89%-0.25%
28
HGLM Models Being a target city and having a higher level of dosage was significantly related to a reduction in violent crime controlling for: Concentrated disadvantage Population density Police resources Correctional population Journal of Quantitative Criminology (2010) 26:165-190.
29
Next Steps Trend in firearm homicide (initial analysis suggests similar impact) Trend in firearms crime Extend beyond 2006
30
Promising Practices Some combination of focused deterrence, communication, data-driven problem solving, & linkage to opportunities, appears promising in reducing gun crime

32
Key Elements Process (how it works) Substance (why it works)
33
Process – Intelligence Led Problem Solving Strategic & tactical understanding of the gun crime problem in specific jurisdictions Highly focused Evidence-based Adaptive & self-correcting
34
Intelligence-led Problem Solving Problem Analysis StrategyImplementation Assessment & Feedback
35
Strategic Intelligence Patterns (rates, trends, historic hot spots – who, what, where, when, why) Is there a network structure (groups, gangs)? Is it connected to drug markets? How “hot” are the hot spots?
36
Tactical Intelligence Who is most at-risk now? Who are they connected to? What are the “hottest” hot spots? Is it connected to open & overt drug markets?
37
Problem Analysis - Specific Tactics COMPSTAT-style crime analysis Systematic incident reviews - Homicide review team
38
Specific Strategies Enforcement Chronic violent offender lists Call-in meetings Directed police patrol gun hot spots Smart prosecution Probation/parole home visits Focused warrant service Intervention/Prevention Direct linkage to services for at-risk populations Mentoring Street-level intervention Moral voice of community Community revitalization
39
Adaptive & Self-Correcting Accountability Feedback mechanism
40
Substance – Effective & Fair Focused deterrence Selective incapacitation Credible deterrence message communicated to at- risk individuals & groups Legitimate; Perceived as fair Procedural & restorative justice Builds informal social control; Neighborhood collective efficacy
41
Legitimacy & Fairness Legitimate; Perceived as Fair Prosecution focused on most violent Call-in meetings offer warning & options (services) Community included
42
Informal Social Control; Neighborhood Collective Efficacy Gain control public space (“breathing space”) Include citizens (have a “say”) Willing to participate because fair Re-assert control
43
Summary -Highly Focused, Evidence- Based Strategies (people & places) “Pulling levers” Aggressive prosecution of most violent & chronic Deterrence message communicated to at- risk populations Combined with offer social support Community voice
44
Risk-Based Strategies Incapacitation Focused Deterrence Limit Opportunity, General Deterrence Compliance through Belief, Stakes in Conformity High Risk Low Risk
45
Balanced Strategies Focused and Fair Substance/TheoryProcess Highly FocusedMulti-agency, Multi-sector Focused Deterrence backed up by incapacitation Data-driven; intelligence- led; research partner Risk CommunicationOffender notification meetings and public education campaign Social Support/Procedural Justice/Restorative Community collaboration
46
Characteristics of Effective Implementation Partnerships (knowledge, resources, credibility) Local, state, federal law enforcement Federal – local prosecution Probation, parole, DOC Social services Community Research partner/analysts
47
Characteristics of Effective Implementation – Who is Needed? Executive level commitment & involvement Line & middle management commitment & involvement Project leader/manager(s) Research partner Real community partners
48
Characteristics of Effective Implementation – What is Needed? Regular meetings –Executive/strategic –Operational/tactical Accountability mechanisms –Are we doing what we said we’d do? –Are we having the intended impact? Sustainability (resources; human capital)
49
Limitations Limited availability of ‘gun-related offense’ data Models assume an ‘on-off’ PSN treatment/dosage effect that started in 2002 and was stable through 2006 Examination assumes equal treatment WITHIN PSN target cities Different ‘starting points’ between PSN target and non- target cities is important (treatment calibrated with need) Some threat of regression to mean (though seems less of a threat when compare PSN target sites by level prosecution)
50
Additional Research Finding Integration of research was positively associated with other implementation components
51
Bivariate Correlations Research Integration Collaborative Implementation Enhanced Prosecution Table 10.Correlations Matrix for Policy Adoption Elements Source: Zimmermann, 2006
52
Lingering Research Questions Is the impact short-term or sustained? –Theoretical Issue –Programmatic Issue What is the impact on individual offenders in contrast to neighborhood/community effects?
53
Lingering Research Questions Which program components are producing the impact? Can we increase the scientific rigor of the tests of these “promising practices?”
