Violent Crime Reduction Roadmap

Working Together to Build Safer Communities

Action 10. Commit to continuous improvement based on data, evidence, and peer-to-peer learning.

Blue bar chart indicating growth with yellow arrow pointing up and to the right. two blue arrows bend into a circle around the chart.

With resources limited and lives at risk, leaders should embrace a culture of learning that assesses every strategy to determine if it is saving lives and reducing violence. This requires engaging with both research partners and multi-sector stakeholders to analyze performance and when necessary, implement course corrections that can maximize impact.

DOJ resources can help localities establish an infrastructure to support continuous improvement and innovation. Key resources are identified below, followed by links to additional resources.

Paving the Way for Project Safe Neighborhoods: SACSI in 10 US Cities (PDF, 353 KB)

The Department of Justice launched the Strategic Approaches to Community Safety Initiative (SACSI) to test data-driven intervention strategies for targeted homicide, youth violence, firearm violence in 9 cities and rape and sexual assault in 1 city. The study found that the SACSI approach, when implemented effectively, is associated with reductions in targeted violent crimes, sometimes by as much as 50 percent. This report highlights the key elements that led to success of SACSI, such as leadership provided by the U.S. Attorney’s Office, the integration of research into planning and intervention strategies, collaborative strategic planning, and implementation of various intervention strategies.

Indianapolis, Indiana was one of the first sites to implement SACSI. Through multi-agency collaboration, Indianapolis used data- and information-driven strategies to reduce firearms violence and homicide, resulting in a 53% reduction of gun assaults and 32% reduction in homicides. This report provides a detailed description of the process of conducting a problem analysis, employing prevention and intervention efforts to significantly reduce gun assaults and homicide rates, and continued monitoring of the effect of this data-driven, interagency, problem-solving approach.

Crime Solutions Program Profile: Operation Ceasefire in Boston, MA

Operation Ceasefire is a problem-solving police strategy that started in Boston, MA and was designed to reduce gang violence, illegal gun possession, and gun violence in communities using a focused deterrence strategy. This program is rated Effective; when implemented in Boston, there were statistically significant reductions in youth homicide, citywide gun assaults, calls for service, and recovered new guns following implementation of the intervention. This program profile provides a description of the program, evaluation findings, and key implementation information.

Disrupting Illegal Firearms Markets in Boston: The Effects of Operation Ceasefire on the Supply of New Handguns to Criminals

Operation Ceasefire is a problem-solving police strategy that started in Boston, MA and was designed to reduce gang violence, illegal gun possession, and gun violence in communities using a focused deterrence strategy. This program is rated Effective; when implemented in Boston, there were statistically significant reductions in youth homicide, citywide gun assaults, calls for service, and recovered new guns following implementation of the intervention. This program profile provides a description of the program, evaluation findings, and key implementation information.

This study evaluated the effectiveness of law enforcement efforts to interrupt the supply of new handguns to criminals in Boston through Operation Ceasefire. Results from the evaluation found that the program’s focus on retail diversion was associated with a decrease in the percentage of new handguns recovered by Boston police. Policy implications are discussed and include the need to develop strategic enforcement programs that target the illegal diversion of new guns from primary markets.

Crime Solutions Practice Profile: Hot Spots Policing 

Hot spots policing strategies focus on small geographic areas or places, usually in urban settings, where crime is concentrated. Through hot spots policing strategies, law enforcement agencies can focus limited resources in areas where crime is most likely to occur. This practice is rated Effective for reducing overall crime and rated Promising for reducing violent, property, public order, and drug and alcohol offenses. This program profile provides a description of the practice and key evaluation findings.

Crime Solutions Program Profile: Chicago Alternative Policing Strategy (CAPS)

This is a community-based program that brings police, local government agencies, and the community together to prioritize problems and prevention efforts in Chicago, Ill. The goal is to solve neighborhood crime problems, rather than react to only to their symptomatic consequences. The program is rated Promising. Police beats or geographical units that implemented the program experienced a statistically significant reduction in crime and calls to 911, compared with police beats that did not. This program profile details the description, methodology, and evaluation outcomes. 

Crime Solutions Program Profile: Comprehensive Anti-Gang Initiative (CAGI)

A crime-focused initiative, designed to address gang-related gun homicides in selected cities. The Comprehensive Anti-Gang Initiative (CAGI) was implemented in 12 select cities in response to increasing gang prevalence across the country. The main purpose of the CAGI was to prevent and reduce gang-related crime. The initiative involved a comprehensive model of suppression (enforcement), prevention, and reentry. The program is rated Promising; there was a significant reduction in gun homicides related to gang crime in cities that implemented the initiative. 

Crime Solutions Program Profile: Geographically Based Focused Deterrence Intervention (Midwest)

A geographically based focused deterrence intervention was implemented in a midwestern city, with the goal of reducing gun violence, particularly gang-related gun violence.  The dual place- and person-based components of focused deterrence strategies typically target gang networks and areas that suffer from high amounts of gang and gun violence. The target area was selected using official police data on the number of shots fired during a specific period of time. There was a statistically significant reduction in confirmed shots fired, residents’ reports of hearing gunshots, and residents’ reports of seeing gang activity. However, there was no statistically significant impact on calls for service for shots fired. The program is rated Promising.

Crime Solutions Practice Profile: Geographically Focused Policing Initiatives

Geographically focused policing initiatives increase the presence and visibility of police officers at specific high-crime locations to significantly reduce crime and disorder. When implementing geographically focused policing initiatives, the target areas may include small places (e.g., crime hot spots, problem buildings), smaller police-defined areas (e.g., beats), neighborhoods and selected stretches of roads or highways, or larger police-defined areas (e.g., precincts). This practice is rated Promising for reducing crime in treatment areas relative to control areas.

Crime Solutions Program Profile: Safe Street Teams (Boston, MA)

Safe Street Teams (SST) is a place-based, problem-oriented policing strategy implemented by the Boston (Mass.) Police Department in response to a sudden increase in violent index crimes. The SST program was designed to reduce violent crime by assigning teams of BPD officers to targeted crime hot spots around the city and requiring them to implement problem-oriented policing strategies to address specific violence-related problems at each site. The program is rated Promising; treatment street units experienced statistically significant reductions in total violent index crime, robbery, and aggravated assault, compared with control street units.
