Overview

Instances of police use and misuse of force are national news stories, as is the rise in gang violence in cities like Chicago. But what drives groups to violence, and is it possible to intervene and prevent it? IPR researchers have some answers.

Communities Partnering 4 Peace (CP4P) Preliminary Individual Results

September 2021

A report by the Northwestern Neighborhood & Network Initiative (N3) looks at the impact of Communities Partnering 4 Peace (CP4P), a Chicago collaboration of outreach and victim services organizations. N3 finds that CP4P has served about 3,600 people since July 2017. N3 concludes, preliminarily, that CP4P successfully locates those people at highest risk of being victims of gun violence, potentially increases positive outcomes such as more education and employment, and potentially reduces the risk of involvement in gun violence.

Reaching and Connecting: Preliminary Results from Chicago CRED’s Impact on Gun Violence Involvement

August 2021

The Northwestern Neighborhood & Network Initiative (N3) examines 234 men who entered the CRED program in 2019 from Roseland and West Pullman in a report. Early results suggest that CRED (a) successfully locates high-risk populations, (b) successfully connects participants to intensive programming, and (c) potentially reduces the risk of involvement of gun violence of its participants in the short term. Overall, the number of fatal and non-fatal gunshot injuries across all CRED participants decreased by nearly 50%, and the number of arrests for violent crimes fell 48% in the 18 months following the start of participation in the program.

New Community Policing Program Shows Some Positive Progress, But Requires More Work

May 2021

N3's report on the Chicago Neighborhood Policing Initiative (CNPI) finds challenges arose due to the pandemic, aftermath of George Floyd, and Chicago’s high rates of shootings and gun deaths.  However, N3 also found that the police and community participants show some positive changes, such as greater police visibility, more police attention to community concerns, and, most importantly, more meaningful interpersonal interactions between residents and police officers.

Why Individuals at the Highest Risk of Gun Violence Choose Chicago CRED

January 2021

This N3 report identifies how a street outreach program run by Chicago CRED (Creating Real Economic Destiny) not only identifies but also engages such individuals. It details the experiences of participants in the program, highlighting how they perceive the violence that surrounds them, as well as why they joined and choose to stay in CRED.

A Network Analysis of Three Weekends of Shootings in Chicago, June 18–July 5

January 2021

This report examines the shootings and homicides that occurred during one of the most severe upticks of gun violence in 2020—the two-week period between Father’s Day and the Fourth of July Weekend, June 18 to July 5, 2020. By delving more deeply into this period, the report aims to illustrate how understanding the networks in which gun violence occurred during an especially deadly outbreak of violence might inform policy and practice.

Managing Multiple Pandemics: How Street Outreach Workers Are Addressing Gun Violence and COVID-19

September 2020

This report details how how street outreach workers are currently dealing with three pandemics: gun violence, the coronavirus, and racism and police violence. Data show that the neighborhoods covered by outreach workers affiliated with Communities Partnering 4 Peace (CP4P) were the very same neighborhoods with Chicago’s highest rates of COVID-19.

New Research Shows That the Typical Homicide Victim Is in Their Late 20s

September 2020

N3’s latest report shows that in 2019 the average age of a homicide victim in Chicago was 29 years of age and the median age was 27 years old, meaning that a typical homicide victim is in his or her 20s. Over the past decade, the median has fluctuated between 24 and 28 years old, and Chicago has seen a 71% decrease in the number of victims 12 or younger since the 1990s.

Review of the Evanston Police Department’s Use of Force Policy

September 2020

The Northwestern Neighborhood and Network Initiative (N3) delivered a report to the City of Evanston reviewing its use of force policy and data for its police department, offering recommendations to strengthen the policy, which in turn, may lead to additional reforms aimed at greater equity, transparency, and accountability. The report was discussed at a city council meeting and is being reviewed by Evanston’s Human Services Committee.

Communities Partnering for Peace (CP4P) Street Outreach: The Moments that Matter

August 2020

As the research partner for CP4P, the Northwestern Neighborhood & Network Initiative (N3) uses quantitative and qualitative methods to study its impact.  While analysis of administrative and survey data illuminates a wide range of behaviors and outcomes, they cannot fully describe the full spectrum of potential participant outcomes. Therefore, CP4P and N3 launched a qualitative study to provide a more holistic account of participants' lives and experiences with street outreach.

Chicago Community Policing Initiative Shows Promise

July 2020

In January 2019, the Chicago Police Department (CPD) in collaboration with the Policing Project at New York University School of Law launched the Chicago Neighborhood Policing Initiative (CNPI). As CNPI’s research and evaluation partner, the Northwestern Neighborhood & Network Initiative (N3) began evaluating CNPI during the initial rollout, and has found results that suggest both community and police believe CNPI to be useful for building trust and fostering meaningful community engagement.

Retraining Police to Reduce Complaints and Misconduct

April 2020

IPR sociologist Andrew Papachristos, IPR postdoctoral fellow George Wood, and Yale’s Tom Tyler conducted a rigorous evaluation of whether training nearly 8,500 officers in procedural justice strategies from January 2012 to March 2016 would reduce use of force. Published in the Proceedings of the National Academy of Sciences, the procedural justice model emphasizes listening and responding to people in the community, and treating the public with dignity, courtesy, and respect.

Preliminary Neighborhood Level Impact Analysis Communities Partnering 4 Peace

March 2020

In the summer of 2017, eight outreach organizations in Chicago joined together to create a comprehensive, long-term intervention to combat gun violence and gang activity. The initiative, Communities Partnering 4 Peace (CP4P), partnered with Northwestern’s Neighborhood and Network Initiative (N3), is mobilizing a four-pillar approach to violence. This brief presents preliminary results of a community-level analysis, looking at what happened to gun violence trends in CP4P treatment communities from 2017–19.

Networks and Police Misconduct

August 2019

A recent analysis by IPR sociologist Andrew Papachristos and his colleagues of police officers’ work networks finds that officers who worked with others who were accused of misuse of force were more likely to also be involved in misuse of force.

The Network Structure of Police Misconduct 

July 2019

In research published in Nature Human Behaviour, IPR sociologist Andrew Papachristos, IPR postdoctoral fellow George Wood, and Daria Roithmayr of the University of Southern California discover that police misconduct is concentrated in networks. They explore the role of gender, race, and tenure in the networks and recommend steps to decrease complaints against officers.

Predicting Police Misconduct

October 2018

Civilian allegations can predict which police officers pose the highest risk for serious misconduct. The allegations can serve as an early warning system to reduce misconduct and save cities money, according to a study co-authored by law professor and IPR associate Max Schanzenbach.
