Other than the drop in numbers, the most striking feature of the decline in European homicide is the change in the socioeconomic profile of killing. Centuries ago rich people were as violent as poor people, if not more so. Gentlemen would carry swords and would not hesitate to use them to avenge insults. They often traveled with retainers who doubled as bodyguards, so an affront or a retaliation for an affront could escalate into a bloody street fight between gangs of aristocrats (as in the opening scene of Romeo and Juliet). The economist Gregory Clark examined records of deaths of English aristocrats from late medieval times to the Industrial Revolution. I've plotted his data in figure 3-7, which shows that in the 14th and 15th centuries an astonishing 26 percent of male aristocrats died from violence -- about the same rate that we saw in figure 2-2 as the average for preliterate tribes. The rate fell into the single digits by the turn of the 18th century, and of course today it is essentially zero.

There are men whom nothing but a physical punishment will bring to reason, and with these we shall have to deal at some time of our lives. A lady is insulted or annoyed by an unwieldy bargee, or an importunate and dishonest cabman. One well-dealt blow settles the whole matter… A man therefore, whether he aspires to be a gentleman or not, should learn to box… There are but few rules for it, and those are suggested by common sense. Strike out, strike straight, strike suddenly; keep one arm to guard, and punish with the other. Two gentlemen never fight; the art of boxing is brought into use in punishing a stronger and more imprudent man of a class beneath your own.

A homicide rate measured in percentage points is still remarkably high, and well into the 18th and 19th centuries violence was a part of the lives of respectable men, such as Alexander Hamilton and Aaron Burr. Boswell quotes Samuel Johnson, who presumably had no trouble defending himself with words, as saying, "I have beat many a fellow, but the rest had the wit to hold their tongues." Members of the upper classes eventually refrained from using force against one another, but with the law watching their backs, they reserved the right to use it against their inferiors. As recently as 1859 the British author of The Habits of a Good Society advised:

The European decline of violence was spearheaded by a decline in elite violence. Today statistics from every Western country show that the overwhelming majority of homicides and other violent crimes are committed by people in the lowest socioeconomic classes. One obvious reason for the shift is that in medieval times, one achieved high status through the use of force. The journalist Steven Sailer recounts an exchange from early-20th-century England: "A hereditary member of the British House of Lords complained that Prime Minister Lloyd George had created new Lords solely because they were self-made millionaires who had only recently acquired large acreages. When asked, 'How did your ancestor become a Lord?' he replied sternly, 'With the battle-ax, sir, with the battle-ax!'"

As the upper classes were putting down their battle-axes, disarming their retinues, and no longer punching out bargees and cabmen, the middle classes followed suit. They were domesticated not by the royal court, of course, but by other civilizing forces. Employment in factories and businesses forced employees to acquire habits of decorum. An increasingly democratic political process allowed them to identify with the institutions of government and society, and it opened up the court system as a way to pursue their grievances. And then came an institution that was introduced in London in 1828 by Sir Robert Peel and soon named after him, the municipal police, or bobbies.

In an influential article called "Crime as Social Control," the legal scholar Donald Black argued that most of what we call crime is, from the point of view of the perpetrator, the pursuit of justice. Black began with a statistic that has long been known to criminologists: only a minority of homicides (perhaps as few as 10 percent) are committed as a means to a practical end, such as killing a homeowner during a burglary, a policeman during an arrest, or the victim of a robbery or rape because dead people tell no tales. The most common motives for homicide are moralistic: retaliation after an insult, escalation of a domestic quarrel, punishing an unfaithful or deserting romantic partner, and other acts of jealousy, revenge, and self-defense. Black cites some cases from a database in Houston:

The main reason that violence correlates with low socioeconomic status today is that the elites and the middle class pursue justice with the legal system while the lower classes resort to what scholars of violence call "self-help." This has nothing to do with Women Who Love Too Much or Chicken Soup for the Soul; it is another name for vigilantism, frontier justice, taking the law into your own hands, and other forms of violent retaliation by which people secured justice in the absence of intervention by the state.

One in which a young man killed his brother during a heated discussion about the latter's sexual advances toward his younger sisters, another in which a man killed his wife after she "dared" him to do so during an argument about which of several bills they should pay, one where a woman killed her husband during a quarrel in which the man struck her daughter (his stepdaughter), one in which a woman killed her 21-year-old son because he had been "fooling around with homosexuals and drugs," and two others in which people died from wounds inflicted during altercations over the parking of an automobile.

Most homicides, Black notes, are really instances of capital punishment, with a private citizen as the judge, jury, and executioner. It's a reminder that the way we conceive of a violent act depends on which of the corners of the violence triangle (see figure 2-1) we stake out as our vantage point. Consider a man who is arrested and tried for wounding his wife's lover. From the point of view of the law, the aggressor is the husband and the victim is society, which is now pursuing justice (an interpretation, recall, captured in the naming of court cases, such as The People vs. John Doe). From the point of view of the lover, the aggressor is the husband, and he is the victim; if the husband gets off on an acquittal or mistrial or plea bargain, there is no justice, as the lover is enjoined from pursuing revenge. And from the point of view of the husband, he is the victim (of cuckoldry), the lover is the aggressor, and justice has been done -- but now he is the victim of a second act of aggression, in which the state is the aggressor and the lover is an accomplice. Black notes:

Those who commit murder… often appear to be resigned to their fate at the hands of the authorities; many wait patiently for the police to arrive; some even call to report their own crimes… In cases of this kind, indeed, the individuals involved might arguably be regarded as martyrs. Not unlike workers who violate a prohibition to strike -- knowing they will go to jail -- or others who defy the law on grounds of principle, they do what they think is right, and willingly suffer the consequences.

These observations overturn many dogmas about violence. One is that violence is caused by a deficit of morality and justice. On the contrary, violence is often caused by a surfeit of morality and justice, at least as they are conceived in the minds of the perpetrators. Another dogma, cherished among psychologists and public health researchers, is that violence is a kind of disease. But this public health theory of violence flouts the basic definition of a disease, namely a malfunction that causes suffering to the individual. Most violent people insist there is nothing wrong with them; it's the victim and bystanders who think there's a problem. A third dubious belief about violence is that lower-class people engage in it because they are financially needy (for example, stealing food to feed their children) or because they are expressing rage against society. The violence of a lower-class man may indeed express rage, but it is aimed not at society but at the asshole who scraped his car and dissed him in front of a crowd.

But another reason for their statelessness is that lower-status people and the legal system often live in a condition of mutual hostility. Black and Cooney report that in dealing with low-income African Americans, police "seem to vacillate between indifference and hostility,… reluctant to become involved in their affairs but heavy handed when they do so." Judges and prosecutors too "tend to be… uninterested in the disputes of low-status people, typically disposing of them quickly and, to the parties involved, with an unsatisfactory penal emphasis." Here is a Harlem police sergeant quoted by the journalist Heather MacDonald:

In an article inspired by Black called "The Decline of Elite Homicide," the criminologist Mark Cooney shows that many lower-status people -- the poor, the uneducated, the unmarried, and members of minority groups -- are effectively stateless. Some make a living from illegal activities like drug dealing, gambling, selling stolen goods, and prostitution, so they cannot file lawsuits or call the police to enforce their interests in business disputes. In that regard they share their need for recourse to violence with certain high-status people, namely dealers in contraband such as Mafiosi, drug kingpins, and Prohibition rumrunners.

Last weekend, a known neighborhood knucklehead hit a kid. In retaliation, the kid's whole family shows up at the perp's apartment. The victim's sisters kick in the apartment door. But the knucklehead's mother beat the shit out of the sisters, leaving them lying on the floor with blood coming from their mouths. The victim's family was looking for a fight: I could charge them with trespass. The perp's mother is eligible for assault three for beating up the opposing family. But all of them were street shit, garbage. They will get justice in their own way. I told them: "We can all go to jail, or we can call it a wash." Otherwise, you'd have six bodies in prison for BS behavior. The district attorney would have been pissed. And none of them would ever show up in court.

Not surprisingly, lower-status people tend not to avail themselves of the law and may be antagonistic to it, preferring the age-old alternative of self-help justice and a code of honor. The police sergeant's compliment about the kind of people he deals with in his precinct was returned by the young African Americans interviewed by the criminologist Deanna Wilkinson:

Dexter: They make worser cause niggas [the police] was fuckin' niggas [youth] up. They crooked theyself, you know what I mean? Them niggas [the police officers] would run up on the drug spot, take my drugs, they'll sell that shit back on the street, so they could go rush-knock someone else.

Reggie: The cops working my neighborhood don't belong working in my neighborhood. How you gonna send white cops to a black neighborhood to protect and serve? You can't do that cause all they gonna see is the black faces that's committing the crimes. They all look the same. The ones that's not committing crimes looks like the niggas that is committing crimes and everybody is getting harassed.

The historical Civilizing Process, in other words, did not eliminate violence, but it did relegate it to the socioeconomic margins.

Quentin [speaking of a man who had shot his father]: There's a chance he could walk, what am I supposed to do?… If I lose my father, and they don't catch this guy, I'm gonna get his family. That's the way it works out here. That's the way all this shit out here works. If you can't get him, get them… Everybody grow up with the shit, they want respect, they want to be the man.
