The best nonfiction books about why people sometimes kill one another

Florida-based historian David Courtwright is best known for his analyses of the history of drug addiction and the drug business in the United States, but this volume is a fact-filled page-turner on America's lethal violence problem. Courtwright describes a frontier culture in which a reputation for violent capability was an essential social asset and persuasively explicates its similarities with the situation that faces single young men in America's underserved inner cities to this day. The interdisciplinary scope of Courtwright's scholarship guarantees that any reader will learn a great deal from his book. I found it unputdownable.   

Rebecca and Russell Dobash had studied men's violence against their female partners for decades and were already heroes of the women's movement when they began interviewing incarcerated killers in Britain. Two fine books have resulted, one focused on men who killed women, the other on men who killed men. It is the former, especially the section on intimate partner homicide, that I find most captivating. The Dobashes skilfully blend national statistics with the self-serving testimony of their interviewees, who minimize their lethal acts as things that "happened" rather than things that they did, and apparently believe themselves to be the victims. These insights are essential.    

It was Calvin Trillin's hilariously enthusiastic stories about the world's best restaurants (most of which seem to be situated in his hometown of Kansas City) that initially made me one of his many fans. Between 1967 and 1982, however, he also wrote a series of long articles for The New Yorker entitled "U.S. Journal," in which he used singular events, often homicides, as the launchpads for tales rich in local history and lifeways. Sixteen of Trillin's best are assembled here. Has anyone written more penetratingly about how rivalries and resentments are embedded in social settings?  

In 1979, Margo Wilson and I were granted access, for research purposes, to police files in Detroit, then the "homicide capital of America." Reading those files, and watching the over-worked homicide detectives in action, we gained great respect for the smart officers who were promoted from the ranks to detective, and I've been fascinated with how they pursue their craft ever since. No one has described this world and what it reveals about everyday lethal violence in America better than reporter David Simon, who was embedded as an "intern" in Baltimore's homicide unit for a year. The hit television series The Wire was based on Simon's book, and I suspect that many fans of that series would like the book even better than the TV show.

People share a complex core of humanity that transcends cultural differences. Rather than being incomprehensibly strange, the passions that move people in "exotic" societies are all too familiar. Compendia of homicide cases in tribal societies that are in many ways different from the one we inhabit support this claim, and my 5th pick is a particularly readable example. Anthropologist Verrier Elwin amassed court records on 107 homicides among the "Bison-Horn Maria" of central India in the first half of the 20th century. The Maria then lived as slash-and-burn horticulturalists and part-time hunter-gatherers, and were, like other "tribals," left to their own devices by the British Raj unless a violent death provoked state intervention. The killings described here are tragic, and the protagonists, though sparsely introduced, fully human.
