Cell Block Tango:
Steps of Misconduct, Over-Policing, and Cycles of Racial Injustice in Chicago’s Criminal Justice System

Author

Courtney Green

Introduction & Motivation

Chicago serves as both a microcosm and a magnifying glass for the systemic failures embedded in the U.S. criminal justice system. For five consecutive years, the city has led the nation in exonerations, which is a devasting testament to entrenched racial bias, police misconduct, and flawed policing practices1. That being said, Chicago is more than an anomaly, it is a focal point within a broader, statewide crisis, and a reflection of nationwide patterns.

This project expands the lens to examine Illinois as a whole, using Chicago as a critical case study to investigate how wrongful convictions and over-policing disproportionately devastate Black and Latino communities. By analyzing exoneration patterns, arrest rates, incarceration data, and demographics at the county level, this work uncovers the ways systemic injustices ripple across Illinois. Chicago’s staggering share of exonerations exposes the extreme, but it also reflects a deeper, structural issue that extends beyond city limits.

Research Questions

  1. What patterns emerge in exoneration data across Illinois counties, and how do they reflect systemic failures in the justice system?
  2. Why does Chicago account for such a disproportionate share of wrongful convictions in Illinois?
  3. Does over-policing disproportionately target marginalized communities, particularly Black and Latino populations?
  4. What role does police misconduct play in wrongful convictions across Illinois? Is there a relationship between misconduct and race?
  5. Can data-driven models identify predictive patterns of wrongful convictions and over-policing across Illinois counties?

Literature Review

This section lays the groundwork for understanding systemic issues within Illinois’ law enforcement system, including over-policing, wrongful convictions, and racial disparities. By combining empirical studies, historical context, and policy analysis, the literature highlights persistent patterns:

  • The over-under-policing paradox, where marginalized communities face aggressive surveillance yet lack adequate protection.
  • Systemic police misconduct and its role in driving wrongful convictions.
  • How race and socioeconomic status intersect to shape crime patterns, policing practices, and perceptions of justice.

By distilling these insights, this review sets the stage for a deeper, more critical analysis of Illinois’ justice system and the structures that sustain its failures.

Citizens’ Perceptions of Over-and Under-Policing: A Look at Race, Ethnicity, and Community Characteristics

Boehme, Cann, and Isom (2020) examine how race, ethnicity, and community characteristics influence public perceptions of policing, shedding light on the over-under-policing paradox. The authors demonstrate how marginalized communities—particularly Black and Latino neighborhoods, experience aggressive over-policing through surveillance and frequent police encounters, while simultaneously being under-protected when it comes to safety and support. This dual dynamic fosters a deep sense of distrust, isolation, and legal cynicism, perpetuating systemic divides. Significantly, their findings emphasize that race remains a consistent predictor of these perceptions, even after accounting for economic conditions and neighborhood characteristics like concentrated disadvantage and ethnic diversity2.

Using data from the PHDCN Community Survey, which captures responses from 8,782 participants across 343 Chicago neighborhoods, the authors employ Hierarchical Linear Modeling (HLM) to analyze how individual, and community-level factors shape perceptions of policing. Their results reveal that while neighborhood context plays a significant role, racialized policing persists, with Black and Latino residents disproportionately reporting over-policing experiences regardless of socioeconomic conditions2.

The study is particularly important to this project for two key reasons. First, it highlights how structural factors—such as poverty, race, and neighborhood composition intersect to produce divergent policing experiences. This intersectionality aligns with the project’s focus on exploring the racialized and systemic roots of policing disparities in Chicago and Illinois as a whole. Second, the research exposes a feedback loop in which over-surveillance and under-service deepen distrust and isolation within marginalized communities. This insight reinforces the project’s aim to uncover how systemic racial biases and inequities sustain harmful policing cycles, particularly in Black and Latino neighborhoods across Chicago2.

Over-Policing Black Bodies: The Need for Multidimensional and Transformative Reforms

Jones-Brown and Williams (2021) provide a critical analysis of over-policing in Black communities, demonstrating how racial disparities in police interactions—such as traffic stops, consent searches, and arrests—are rooted in systemic biases that criminalize Black identity. Drawing on both quantitative data and qualitative accounts, the authors reveal the psychological toll of aggressive policing, which fosters a feedback loop of fear, mistrust, and isolation. High-profile cases like the deaths of George Floyd and Breonna Taylor serve as stark representations of this broader issue, amplified by social media as a tool for documenting police brutality. Meanwhile, mainstream media often mischaracterizes Black-led protests, further reinforcing harmful stereotypes. Positioning these patterns within a historical context—referencing the 1967 Katzenbach Report and the War on Drugs, the authors expose the longstanding structural roots of racialized policing, particularly relevant to cities like Chicago3.

Jones-Brown and Williams’ study is integral context for the research for several reasons. First, it underscores how structural racism and historical policy decisions continue to drive over-policing in Black communities, a phenomenon reflected in Chicago’s policing data. Second, it highlights the dual perspective of quantitative evidence and qualitative lived experiences, an approach I aim to incorporate into my analysis to capture both the scope and human impact of over-policing. Lastly, their reform recommendations offer a foundation for addressing systemic disparities, aligning with my goal of examining how community-driven solutions can disrupt harmful policing cycles3. By placing over-policing within a historical and structural framework, this study provides a comprehensive understanding of the issue and offers pathways for transformative change. These insights directly support the project’s examination of how racialized policing practices and systemic corruption perpetuate injustice in Chicago’s Black communities3.

Chicago Ranks No. 1 in Exonerations for 5th Year in a Row, Accounting for More Than Half of National Total

Heather Cherone (2023) highlights Chicago’s troubling distinction as the nation’s leader in wrongful convictions, with Cook County alone accounting for over half of all U.S. exonerations in 2022. Drawing on data from the National Registry of Exonerations, the analysis uncovers systemic patterns of police misconduct, racial disparities, and institutional resistance to reform—issues central to this project’s examination of injustice within Illinois’ criminal justice system1.

The article reveals the disproportionate effect of wrongful convictions on Black and Latino communities, underscoring the racialized nature of policing in Chicago. At the core of this crisis is police misconduct, exemplified by officers like Ronald Watts and Reynaldo Guevara, whose corrupt practices—ranging from extortion to framing suspects—are linked to a significant share of exonerations. These patterns not only devastate individuals and their communities but also impose a staggering financial burden on the city. In 2022, Chicago spent $98 million settling police misconduct cases, with the 2023 budget allocating another $82 million, signaling the immense economic cost of systemic failures. Despite the federal consent decree issued in 2017 to address these issues, the Chicago Police Department remains only 3% compliant, reflecting deep institutional resistance to change1.

This analysis provides a critical foundation for the project. By examining exoneration data, it highlights the role of racialized policing practices and systemic misconduct in perpetuating wrongful convictions. Chicago’s prominence in these statistics offers a unique lens through which to explore broader patterns of injustice across Illinois, serving as both a focal point and a microcosm of nationwide systemic failures. Additionally, the data-driven approach of the National Registry of Exonerations aligns closely with this project’s methodology. While not replicating the study, this project builds upon its findings by conducting further analysis of Illinois exoneration trends to uncover how race, police misconduct, and institutional barriers contribute to these systemic injustices.
