Crime: Its Causes and Remedies

A Lombroso Mini-Classic by Graeme R. Newman and Claude

Cesare Lombroso was one of the founders of modern criminology—and one of its most controversial figures. Best remembered for his theory of the “born criminal,” Lombroso also devoted enormous attention to the social, economic, environmental, and institutional forces that shape criminal behavior.

First published in English in 1911, Crime: Its Causes and Remedies ranges remarkably widely. Lombroso examines climate, poverty and wealth, alcohol, education, family background, heredity, age, sex, immigration, urbanization, prisons, political conditions, and criminal associations. He then turns from explanation to prevention, asking what governments and criminal justice systems can actually do about crime.

This Read-Me.Org Modernize Classic makes Lombroso’s sprawling original accessible to a new generation. The abridged and adapted edition follows the three-part structure of the original—the causes of crime, its prevention and treatment, and the application of criminal anthropology to punishment—while providing historical context and critical commentary.

Lombroso’s work contains ideas that now seem strikingly modern alongside others—including his racial theories and biological determinism—that have long been rejected. The result is not merely a historical curiosity, but a fascinating case study in the possibilities and dangers of attempting to make crime a subject of scientific measurement. The volume also considers Lombroso’s continuing relevance to contemporary questions about imprisonment, alcohol and violence, environmental influences on crime, risk prediction, and the relationship between biology and behavior.

A compact introduction to a foundational—and deeply controversial—work in the history of criminology.

The perfect storm. An analysis of the processes that increase lethal violence in Mexico after 2006 

By Iván Flores Martínez & Matthew Phillips 

Research on ‘the War on Drugs’ in Mexico finds that military interventions increase lethal violence in the country. However, these studies fail to account for other processes that may be driving the behavior of lethal violence in the Mexican municipalities. We find confirmation that these rival processes influence the relative impact that military interventions have on lethal violence. In particular, we find that seasonality in violence, competition for scarce resources and PAN’s governance in the municipalities are associated with higher levels of lethal violence, as measured by the young male homicide rate. We argue that the literature may have overestimated the effect that military interventions have in lethal violence in municipalities and that other drivers of violence should be taken into account to accurately measure the impact that military interventions have on lethal violence.

Joint Enterprise: A view over time

By Liat Tuv, Helen Mills, Nisha Waller

The past two decades have seen a sustained rise in multi-defendant homicide prosecutions

This report tracks multi-defendant homicide prosecutions in England and Wales and the concerns they raise around fairness, youth involvement, and racial disproportionality. Drawing on Home Office and CPS data from 2005–2024, it finds that prosecutions involving multiple defendants have become more common, with young people disproportionately represented among those convicted. It also highlights persistent racial disparities and increasingly severe sentencing outcomes for those convicted.

The report situates these findings within wider academic and policy debates on joint enterprise and shared responsibility in serious crime. Authors make the case for government attention and intervention on three key issues: 

  • Narrow the scope of the law: Via a workable test for when someone can be held liable for the crimes of another.

  • Proportionate sentencing: With a separate sentencing framework for secondary parties.

  • Greater transparency and accountability: Requiring prosecutors to state each defendant's individual conduct and intent, and identify possible alternative charging.

How crime rates in NSW compare to the rest of Australia

By Caitlin Bennett and Jackie Fitzgerald

AIM To compare crime and safety in New South Wales (NSW) with other Australian states and territories for violent and property crime. METHOD Crime data is considered from both police administrative systems and crime victimisation surveys. Police-recorded crime statistics for the year 2023 were obtained from the national collection collated and standardised by the Australian Bureau of Statistics (ABS). Victimisation surveys gather self-reported experiences of crime from a representative sample of the population. ABS crime victimisation surveys include the Crime Victimisation Survey (2021/22, 2022/23, 2023/24), the Personal Fraud Survey (2023/24), and the Personal Safety Survey (2021/22). In the case of some low prevalence offences, survey data was pooled across multiple years to improve victimisation estimates. NSW victimisation rates and recorded crime rates were compared with other states and territories, and the national average. Comparisons were produced for a range of violent and property crime offences available in the various sources. Statistical significance for the survey data was determined at the 95% confidence level. RESULTS NSW consistently records some of the lowest crime victimisation rates nationally for many violent and property offences. The specific offences for which NSW shows very low comparative crime rates are: murder, physical assault, robbery, break and enter, motor vehicle theft, malicious damage and theft from motor vehicle. Sexual assault, however, stands out as an offence of concern. NSW rates from police-recorded crime statistics and the Personal Safety Survey suggest NSW is at the higher end of the national range, though not significantly different from the national average. Rates of domestic violence and fraud in NSW appear to be comparable to the national average, with no significant differences detected. CONCLUSION Overall, the analysis demonstrates that crime rates in NSW are generally low compared to other Australian states and territories. Sexual assault rates in NSW are the main area of concern. These findings suggest that while NSW is generally safer than elsewhere in Australia, ongoing attention to sexual assault prevention and support is warranted.

VIOLENT AND VIBRANT: MEXICO’S AVOCADO BOOM AND ORGANIZED CRIME

By Romain Le Cour Grandmaison and Paul Frissard Martinez

The contemporary boom of global avocado consumption has drawn attention to Mexico’s industry and the expanding criminal networks that surround it. In fact, avocado production and exports – both to the United States and the European Union − display worrying signs of criminal organizations being involved in the market, human rights violations, and environmental and health impacts.

Criminal Nucleation and Phase Transitions: A Nonlinear Framework for Organized Violence in Mexico (2000–2024)

By Araceli Vázquez-Ocaña and Alan Alberto Ramírez-Guevara

This study proposes a non-linear analytical framework, inspired by phase-transition theory, to explain abrupt regime shifts in organized violence within weak institutional systems.Using Mexico (2000-2024) as a primary case, we demonstrate that criminal violence does not escalate linearly but undergoes a "phase transition" once specific thresholds are crossed. We introduce the Criminal Nucleation Framework to model the emergence and persistence of criminal cells through three dimensions: the institutional activation barrier (ΔG), the critical organizational size (r*), and the growth constant (k). Empirical validation shows a structural rupture between 2007 and 2010, where homicide rates shifted from a stable regime (8.5–10 per 100k) to a chronic state (25–29 per 100k). By operationalizing a comparative Kinetic Risk Index (R = k/ΔG), the framework classifies cities into distinct systemic states rather than providing point predictions. The findings suggest that once a system exhibits hysteresis, reactive force is structurally insufficient; instead, policy must focus on increasing the activation barrier to prevent spontaneous criminal formation.

Unequal by the gun: Four decades of the Black-White firearm homicide gap 

By Alex Knorre , John MacDonald 

 Background: Firearm homicide is a leading cause of death in the United States, with substantial racial disparities documented over time. Black Americans experience disproportionately higher rates of firearm homicide compared to White Americans, reflecting long-standing social, economic, and structural inequities. This study contributes to understanding the magnitude and trends of this disparity. Objective: We investigate the Black-White population-level disparity in firearm homicide rates over 45 years in the United States and estimate the fraction of excess deaths in the Black population attributable to firearm homicides. Methods: We measure racial disparities in firearm homicides as the ratio of ageadjusted rates between Black and White populations. Using annual national firearm homicide and population data from CDC WONDER (1979–2023), disaggregated by race, age, and sex, we calculate age-adjusted Black–White mortality ratios by year and sex, as well as the number of excess Black firearm homicide deaths attributable to these disparities. Results: After a steady period of 1990-2010, the Black-White disparity began increasing and peaked in 2020 when the firearm homicide rate in males was 10.38 times higher in Blacks than Whites. There were 31,202 excess firearm homicides of Black people attributed to the Black-White racial disparity in 2021-2023. Conclusions: Despite significant declines in firearm homicides during the 1990s, the relative racial gap in firearm homicide has persisted and grown, reflecting the unequal burden of violence borne by the Black population during both declines and surges of violence.

The Highest Rates of Gun Homicides Are in Rural Counties

By Chandler Hall

Since gun homicides in America spiked in 2020 and peaked in October 2021, much of the reporting related to gun violence has centered around the nation’s big cities. Forgotten in this conversation is how rural America is similarly dealing with the crisis of gun violence. Gun violence anywhere is unacceptable—whether in our largest cities, suburbs, or smallest communities. And when half of all shootings occur outside of large cities, focusing exclusively on individual cities comes at the expense of achieving meaningful and long-lasting safety for all Americans. Instead of politicizing crime and community violence, we must recognize that gun violence is a uniquely American public health crisis that harms every community, regardless of size or political leanings.

Unsolved Shootings: Why and How to Boost Clearance Rates 

By PHILIP J. COOK

Approximately 75,000 people in the United States were shot by a criminal assailant in 2024, yet most of those shootings did not result in an arrest.

In this HFG Research and Policy in Brief, Philip J. Cook, professor emeritus at Duke University, explores the gap between the minority of shootings that are solved and those that go unsolved.

“There is a strong argument for improving police performance in investigating serious crimes of violence,” Cook writes in Unsolved Shootings: Why and How to Boost Clearance Rates. “What is at stake is public safety and the basic duty of the police to serve the public.”

Cook examines the importance of arresting and prosecuting perpetrators of serious violence, the validity of “clearance rates” as a performance indicator for police departments, and what can be done by police to increase the success rate for criminal investigations—citing examples from Chicago, Denver, and other cities.

The Psychology Of Misconduct, Vice, And Crime: A Study of Conduct, Responsibility, and Moral Failing

bby Bernard Hollander (Author), Graeme Newman (Introduction)

Why do people do what they know is wrong—and how much responsibility should they bear for their actions?

First published in 1922, Bernard Hollander’s The Psychology of Misconduct, Vice, and Crime: A Study of Conduct, Responsibility, and Moral Failing is a fascinating early attempt to understand wrongdoing through psychology rather than through moral condemnation alone. Drawing on twenty-five years of medical practice with patients suffering from nervous and mental disorders, Hollander examines the impulses, habits, emotions, circumstances, and failures of self-control that can lead ordinary people toward destructive or criminal behavior.

Moving across the emerging fields of psychology, psychiatry, and criminology, Hollander asks questions that remain strikingly familiar today. How do heredity and environment shape conduct? Why can one person resist temptation while another cannot? What roles do opportunity, habit, intoxication, anger, fear, acquisitiveness, and sexual desire play in misconduct? And at what point should psychological impairment affect our judgment of moral and legal responsibility?

Across twelve wide-ranging chapters, Hollander investigates the psychological foundations and causes of misconduct before turning to alcohol and drug habits, aggression and violence, suspicion and deceit, theft and crimes for gain, fear of consequences, sexual conduct, egotism and domination, moral weakness, responsibility, and treatment.

Of particular interest to readers of criminology is Hollander’s rejection of simplistic explanations based entirely upon free will. He sees behavior as emerging from the interaction of predisposition, upbringing, social environment, opportunity, competing motives, and the individual’s capacity for inhibition and self-control. His treatment of professional offenders also distinguishes calculated criminality from impulsive or psychologically troubled misconduct—an early recognition that there is no single psychological type called “the criminal.”

Hollander’s science is unmistakably that of his era. Some of his terminology, assumptions about heredity and mental deficiency, views of sexuality, and continuing interest in phrenology have long since been rejected or superseded. Yet this is precisely what makes the book valuable as a historical document: it captures a formative period when psychology, psychiatry, medicine, and criminology were struggling to replace simple categories of vice and wickedness with explanations based on individual differences and the causes of human behavior.

At the same time, Hollander frequently argues against indiscriminate punishment. He considers upbringing, poverty, physical and mental condition, temptation, and circumstance; questions whether fear and punishment genuinely reform offenders; and advocates individualized treatment rather than a single remedy for every form of misconduct.

This 2026 Read-Me.Org Classic Reprint, designed and edited with a new introduction by Graeme R. Newman, preserves Hollander’s historical arguments and period terminology while correcting obvious OCR and typographical defects, regularizing punctuation, and converting spelling to contemporary American English.

More than a century after its first appearance, The Psychology of Misconduct, Vice, and Crime offers historians, criminologists, psychologists, criminal-justice students, and general readers a provocative window into the origins of modern thinking about crime, deviance, self-control, treatment, and human responsibility.

Stop Thief: A Study of Crime in America

by Col. V. M. Masten (Author), Graeme Newman (Introduction)

What did Americans believe caused crime a century ago—and what did they think should be done about it?

First published in 1921, Stop Thief is a forceful and revealing examination of crime, punishment, policing, prisons, and social disorder in Progressive-Era America. Written by Col. V. M. Masten, the book captures a nation deeply concerned about rising crime and fiercely debating whether criminals should be deterred, punished, rehabilitated, or reformed.

Across eight wide-ranging chapters, Masten addresses immigration and crime, criminal influence and “crime by suggestion,” the courts and judges, prison reform, correctional regimes, professional sport and gambling, and proposals for improving probation, sentencing, and prison administration.

Masten is an uncompromising writer. He challenges the growing rehabilitative philosophy of his period and argues instead for discipline, deterrence, personal responsibility, and the vigorous enforcement of law. Yet some of his observations—particularly his concern with gambling, criminal association, and the ways people learn criminal behavior from others—anticipate debates that remain remarkably current.

At the same time, Stop Thief is very much a document of 1921 America. Its discussions of immigration, race, heredity, and social fitness contain prejudices and pseudo-scientific assumptions characteristic of parts of Progressive-Era criminological writing. This edition preserves that language rather than disguising or rewriting it, allowing the book to be read critically as an important historical source.

This new Read-Me.Org edition reproduces the complete original text, corrected for scanning and transcription errors, and includes a new introduction by criminologist Graeme R. Newman, placing Masten and his arguments within the history of American crime, criminal justice, immigration, and penal reform.

Essential reading for students and readers interested in criminology, criminal justice, American social history, policing, prisons, immigration history, and the Progressive Era, Stop Thief offers something more valuable than a modernized account of the past: it allows us to encounter the American debate over crime as it was actually being conducted more than a century ago.

London Prisons: A Retrospective

by Graeme R. Newman

In 1862, Henry Mayhew and John Binny walked into eleven of London's most notorious institutions — Newgate, Millbank, Pentonville, Brixton, the prison hulks at Woolwich, Coldbath Fields, Tothill Fields, Wandsworth, Holloway, the House of Detention at Clerkenwell, and Horsemonger Lane — and wrote down exactly what they saw: the governors, the warders, the chaplains, and the prisoners themselves, in their own words.

This edition brings that record back to life. Each chapter has been fully rewritten in modern prose while preserving every fact, every interview, and every argument the original authors made — from their case against purposeless hard labour to their unflinching accounts of the convict nursery, the condemned cell, and the boy discharged from prison with no one waiting at the gate.

A new introduction and retrospective, written for this edition, follows these institutions into the present: which ones were demolished, which became galleries, cathedrals, and post offices — and which are still open today, cited in current inspection reports for the very same overcrowding and neglect that Victorian reformers were fighting a century and a half ago.

What you'll find inside: • Eleven Victorian prisons, reconstructed room by room, cell by cell • Real testimony from governors, chaplains, and prisoners — first offenders and lifelong professionals alike • A frank, often moving record of Victorian London's poorest and most desperate • A new historical retrospective connecting each institution to its fate today

Part social history, part true crime, part uncomfortable mirror — London Prisons: A Retrospective is a door-by-door tour of a city's conscience, then and now.

London and Its Criminals: A Portrait of London's Underworld in the 1920s

by Nettly Lucas (Author), Graeme Newman (Introduction)

Step into the hidden London of the 1920s—a city of fashionable hotels and crowded streets, respectable suburbs and shadowy back rooms, Scotland Yard detectives and professional criminals who made deception, burglary, fraud and blackmail their trade.

First published in 1926, London and Its Criminals is Netley Lucas’s remarkable journey through the criminal underworld of interwar London. Rather than simply recounting celebrated crimes, Lucas sets out to describe criminals themselves: how they lived, where they gathered, the methods they used, the slang they spoke, and the elaborate machinery of policing that pursued them.

The result is an extraordinary period portrait of crime and criminal justice.

Lucas takes his readers inside Scotland Yard and its Criminal Record Office, explaining the growing importance of fingerprints, criminal records and systematic detection. From there he ventures into a very different London—the world of professional burglars, pickpockets, confidence tricksters, jewel thieves, forgers, blackmailers and criminal gangs. He introduces his readers to figures he describes as the “Kings” and “Queens” of the Underworld: men and women who move between cheap public houses, prosperous suburban homes, exclusive restaurants and fashionable hotels while living secret criminal lives.

Among the book’s most striking chapters are Lucas’s accounts of “master criminals” and “crooked women.” His characters include expert burglars, ingenious forgers, sophisticated jewel thieves and accomplished confidence tricksters. Some are frightening, some ingenious, some surprisingly ordinary. Again and again Lucas emphasizes the unsettling proximity of the criminal world to respectable society.

Yet London and Its Criminals is more than a gallery of rogues. Lucas was writing at a moment when attitudes toward crime and punishment were beginning to change. He opens the book by discussing the emerging scientific study of crime, criminal psychology, rehabilitation and the limitations of imprisonment—questions that remain central to debates about criminal justice a century later.

Lucas is also an unusually provocative guide. He claims familiarity with criminals themselves and repeatedly describes conversations, meals and encounters with people operating on the wrong side of the law. His London is consequently not the London of official police reports alone. It is a city observed from its restaurants, streets, clubs, pubs, courtrooms and criminal meeting places.

Modern readers should approach some of Lucas’s language, assumptions and sweeping judgments as products of their time. That is also part of the historical importance of the book. It provides a vivid primary-source window into how crime, policing, punishment, class and the urban underworld were represented during the 1920s.

This new Read-Me.Org Classic Reprint presents Lucas’s fascinating account to a new generation of readers, accompanied by a detailed new Introduction by Graeme Newman that places the work in its historical and criminological context.

For readers interested in true crime, criminology, Scotland Yard, policing, criminal history, London history, organized crime and the social history of the 1920s, London and Its Criminals offers a fascinating journey into a vanished—but sometimes surprisingly familiar—criminal world

The Devil Made Him Do It

A Forgotten Classic of Criminological Thought—Reintroduced for the Twenty-First Century

Originally published in 1918 and now carefully edited and introduced by Graeme R. Newman, The Criminology of Crime and Criminals: Medical, Biological and Psychological restores Charles Mercier’s groundbreaking exploration of crime, punishment, criminal behavior, and social order.

Long before modern criminology embraced concepts such as situational crime prevention, environmental opportunity, offender decision-making, and restorative justice, Mercier argued that crime cannot be explained by biology, psychology, or environment alone. Instead, criminal behavior emerges from the interaction between human nature and circumstance, between personal disposition and criminal opportunity.

Rejecting the popular theories of his day, Mercier challenges the notion of the “born criminal” and dismisses simplistic environmental explanations of lawbreaking. His provocative and highly original analysis examines:

  • The psychological foundations of criminal conduct

  • The roles of instinct, reason, desire, self-control, and will

  • How opportunity and temptation shape criminal action

  • The classification of crimes and criminals

  • The relationship between crime, morality, and society

  • The purposes of punishment: deterrence, retaliation, reform, and reparation

  • The prevention, detection, and punishment of crime

Mercier’s central insight—that criminals are not a separate species but ordinary human beings responding differently to circumstances—remains strikingly relevant more than a century later.

Graeme R. Newman’s contemporary introduction places Mercier within the broader history of criminological thought and connects his ideas to modern developments in crime prevention and criminal justice. Together, Mercier and Newman illuminate enduring questions that continue to shape public policy and scholarly debate:

Why do people commit crimes? How should society respond? Is prevention more effective than punishment?

Part intellectual history, part criminological theory, and part social philosophy, this edition offers a fascinating window into the origins of modern criminology and the continuing struggle to understand crime and criminals.

Essential reading for students and scholars of criminology, criminal justice, sociology, psychology, legal history, and anyone interested in the causes of crime and the future of punishment.

Crime, Insanity And Affliction: Three Studies in Social Pathology

by Graeme Newman (Editor), Charles Mercier (Author)

Why do people commit crime? When does mental illness diminish responsibility? Should punishment always follow wrongdoing?

More than a century before modern debates about criminal responsibility, forensic psychiatry, and the treatment of mentally ill offenders, the distinguished British physician Charles Mercier confronted these enduring questions with remarkable clarity and originality.

In Crime, Insanity and Affliction, Mercier explores the complex relationship between criminal behaviour, mental disorder, and human suffering. Rejecting simplistic explanations, he argues that crime cannot be understood apart from the biological, psychological, and social forces that shape human conduct. His examination ranges from drunkenness, epilepsy, intellectual disability, and mental illness to questions of moral responsibility, punishment, and the proper role of the criminal law.

Although written in the early twentieth century, many of Mercier's observations anticipate debates that continue today. His discussion of diminished responsibility, the treatment of mentally ill offenders, addiction, and the limits of punishment remains surprisingly relevant in an era still struggling to balance justice, compassion, and public safety.

This new Read-Me edition presents Mercier's influential work with a new editorial introduction that places his ideas within the development of modern criminology, forensic psychiatry, and criminal justice. It also examines where Mercier's conclusions have been confirmed, where later research has challenged them, and why his work continues to deserve the attention of students, scholars, and general readers alike.

More than a historical curiosity, Crime, Insanity and Affliction is a thoughtful exploration of one of society's oldest and most difficult questions: how should we judge those whose minds, circumstances, or afflictions place them beyond the ordinary boundaries of responsibility?

The Biology of Conduct Disorders

The book that criminology forgot — and urgently needs to remember.
Arthur M<ercier (Author). Graeme Newman (Editor and Introduction).

First published in 1918 by the University of London Press, Charles Arthur Mercier's Conduct and Its Disorders, Biologically Considered, published by Macmillan in 1911 is one of the most rigorous, most readable, and most unjustly neglected works in the history of criminological thought. Now reissued as The Biology of Conduct Disorders, with a major critical introduction by Graeme R. Newman, it arrives at a moment when the questions it raises — about criminal intent, biological disposition, the limits of punishment, and the poverty of criminological theory — are more pressing than ever.
Mercier was no armchair theorist. As medical officer of lunatic asylums, consulting physician at criminal trials, and the only systematic student of conduct as a science, he brought to the study of crime a combination of clinical experience and biological rigour that the field had not seen before and has rarely matched since. His target was the prevailing chaos of criminological thought — above all the Continental school of Lombroso, which he dismantled with surgical precision — and his method was the application of praxiology, his own science of conduct, to the specific problem of criminal action.

What Mercier argued — and why it still matters:

  • Every criminal act is the product of two factors: an internal factor (the biological constitution of the offender) and an external factor (circumstance and opportunity). Ignoring either produces not criminology but ideology.

  • The turpitude of the criminal and the gravity of the crime are entirely separate questions — and confusing them has produced centuries of unjust punishment.

  • Punishment should be calibrated to intention, not outcome: the man who intends murder and fails is more culpable than the man who kills by accident, whatever the body count.

  • Statistical criminology — mass data gathered from convicted prisoners — cannot produce a science of crime. Only the study of individual criminal action, grounded in biology, psychology, and jurisprudence together, can do that.

  • Certain acts currently outside the law (stealing the use of a thing; deliberate breach of contract) deserve criminal status; certain acts currently criminalised do not.

This new edition includes a critical introduction by Graeme R. Newman, Distinguished Professor Emeritus at the School of Criminal Justice, University at Albany, and one of the most provocative and original voices in the study of crime, deviance, and punishment. Author of Comparative Deviance: Perception and Law in Six Cultures, The Punishment Response, Just and Painful: A Case for the Corporal Punishment of Criminals, and Civilization and Barbarism: Punishing Criminals in the Twenty-First Century — and, as Colin Heston, of darkly satirical fiction including The Tommie Felon Show, Miscarriages, and Holy Water — Newman brings a unique authority to this text. Writing with the unflinching directness that earned him national television appearances and a reputation as the most uncomfortable conscience in American criminology, he traces the connections between Mercier's 1918 arguments and the debates that have defined — and divided — the field ever since.
"With the exception of logic, there is no subject on which so much nonsense has been written as this of criminality and the criminal." — Charles Arthur Mercier, 1918
Essential reading for students and scholars of criminology, criminal justice, the history of psychiatry, legal theory, and the philosophy of punishment — and for anyone who has ever wondered why, after two centuries of criminal science, we understand so little about why people commit crimes and what we should do about it.

Homicide in Victoria: female perpetrators of murder and manslaughter, 1860 to 1920 

By Victoria Nagy

Records from the Central Register of Female Prisoners permit a longitudinal analysis of ninety-five women convicted of murder and manslaughter in Victoria between 1860 and 1920. The data show the similarities and differences between the women convicted of these homicide offenses. An examination of the women’s socioeconomic profiles, occupations, ages, migrations, and victims reveals the links between their crimes and their punishment.

Hispanic Victims of Lethal Firearms Violence in the United States

By Terra Wiens  

  KEY FINDINGS AND RECOMMENDATIONS KEY FINDINGS ■ In 2023, more than 5,700 Hispanics were killed by guns. That year, 3,284 Hispanics died in gun homicides, 2,198 died in gun suicides, 63 died in unintentional shootings, and 202 died in other circumstances (including legal interventiona and undetermined intent). ■ More than 83,000 Hispanics were killed by guns between 2002 and 2023. During this period, 51,780 Hispanics died in gun homicides, 27,160 died in gun suicides, and 1,220 died in unintentional shootings. ■ Most Hispanic murder victims are killed with guns. In 2023, guns were used in more than three-quarters of the homicides where the victims were Hispanic. The latest data show that for homicides where the victim was Hispanic and a gun was used, 53.0 percent of these shootings involved a handgun. ■ The homicide victimization rate for Hispanics in the United States is higher than the homicide victimization rate for whites. The Hispanic homicide victimization rate in 2023 was 6.3 per 100,000. In comparison, the homicide victimization rate for whites was 2.9 per 100,000. ■ As a result of the limitations in current data collection, the total number of Hispanic victims is almost certainly higher than the reported numbers suggest. Government agencies often report data on race but not on ethnic origin. Recognizing the changing demographic landscape in the United States, it is clear that fully documenting such victimization is a crucial step in preventing it. RECOMMENDATIONS Governmental agencies that collect data on death and injury should obtain complete information on the ethnic origin of individuals in addition to their race. This will ensure complete and accurate data collection on Hispanic victims of lethal violence. ■ Individual-level ethnic origin information should be captured by all governmental agencies, regardless of department, and at all levels — local, state, and national — for all pertinent users and subjects of agency services. ■ Individual-level ethnic origin information should be self-reported and not based solely on a person’s surname or other measure. ■ All public access data and published reports issued by governmental agencies should include information on ethnic origin in addition to race. ■ The U.S. Department of Justice should issue periodic or special reports on Hispanic victimization. ■ States with a substantial proportion of Hispanic residents should issue periodic or special reports on Hispanic victimization and deaths due to all causes, including violence. Improved data collection is essential to fully understanding the scope of lethal firearms violence against Hispanics and helping develop effective measures to reduce such violence. At the same time additional efforts, both supporting current programs and activities as well as identifying new violence-reduction opportunities and approaches, should include the following: ■ Support for community-based violence intervention programs that are holistic and encourage participation by all stakeholders. ■ Educational efforts to better inform Hispanics of the risks associated with bringing a firearm into the home as measured by increased risk for homicide, suicide, and unintentional firearm deaths compared to how rarely guns are used in justifiable homicides. This is especially important in the face of current coordinated efforts by the gun industry targeting Hispanics as potential first-time gun buyers.b ■ Improved access to resources for victims and survivors of domestic violence. ■ Identification of anti-trafficking measures that could help interrupt the flow of illegal firearms into impacted communities   

Pathways of post-conflict violence in Colombia

By Juan Albarracín, Juan Corredor-Garcia, Juan Pablo Milanese, Inge H. Valencia & Jonas Wolff

Violence in post-conflict settings is often attributed to a post-war boom in organized crime, facilitated by the demobilization of armed groups and the persisting weakness of the state. The article argues that this is only one pathway of post-conflict violence. A second causal pathway emerges from the challenges that peace processes can constitute for entrenched local political orders. By fostering political inclusion, the implementation of peace agreements may threaten subnational political elites that have used the context of armed conflict to ally with armed non-state actors. Violence is then used as a means to preserve such de facto authoritarian local orders. We start from the assumption that these two explanations are not exclusive or competing, but grasp different causal processes that may well both be at work behind the assassination of social leaders (líderes sociales) in Colombia since the 2016 peace agreement with the FARC guerrilla. We argue that this specific type of targeted violence can, in fact, be attributed to different, locally specific configurations that resemble the two pathways.
