When Rudy Giuliani ran for mayor of New York City in 1. It was a comfortable position for a former federal prosecutor with a tough- guy image, but it was more than mere posturing. Since 1. 96. 0, rape rates had nearly quadrupled, murder had quintupled, and robbery had grown fourteenfold. New Yorkers felt like they lived in a city under siege. Throughout the campaign, Giuliani embraced a theory of crime fighting called .
Kelling in an influential article in The Atlantic. But if you cracked down on small crimes, bigger crimes would drop as well. Giuliani won the election, and he made good on his crime- fighting promises by selecting Boston police chief Bill Bratton as the NYPD's new commissioner. Bratton had made his reputation as head of the New York City Transit Police, where he aggressively applied broken- windows policing to turnstile jumpers and vagrants in subway stations. With Giuliani's eager support, he began applying the same lessons to the entire city, going after panhandlers, drunks, drug pushers, and the city's hated squeegee men. And more: He decentralized police operations and gave precinct commanders more control, keeping them accountable with a pioneering system called Comp. Stat that tracked crime hot spots in real time. The results were dramatic. In 1. 99. 6, the New York Times reported that crime had plunged for the third straight year, the sharpest drop since the end of Prohibition. Since 1. 99. 3, rape rates had dropped 1. Giuliani was on his way to becoming America's Mayor and Bratton was on the cover of Time. It was a remarkable public policy victory. But even more remarkable is what happened next. Shortly after Bratton's star turn, political scientist John Di. Iulio warned that the echo of the baby boom would soon produce a demographic bulge of millions of young males that he famously dubbed . But even though the demographic bulge came right on schedule, crime continued to drop. By 2. 01. 0, violent crime rates in New York City had plunged 7. All in all, it seemed to be a story with a happy ending, a triumph for Wilson and Kelling's theory and Giuliani and Bratton's practice. And yet, doubts remained.

Lead: America's Real Criminal Element The hidden villain behind violent crime, lower IQs, and even the ADHD epidemic. My apologies for any confusion caused by the way I screwed up the numbering on the first story I posted from this series. As my draft approached seven hundred pages. For one thing, violent crime actually peaked in New York City in 1. Giuliani- Bratton era. By the time they took office, it had already dropped 1. Second, and far more puzzling, it's not just New York that has seen a big drop in crime. In city after city, violent crime peaked in the early '9. Washington, DC, didn't have either Giuliani or Bratton, but its violent crime rate has dropped 5. Dallas' has fallen 7. Los Angeles: 7. 8 percent. There must be more going on here than just a change in policing tactics in one city. When I started research for this story, I worked my way through a pair of thickcriminology tomes. One chapter regaled me with the . Unfortunately, the theory doesn't seem to hold water—for example, crime rates have continued to drop recently despite our prolonged downturn. Another chapter suggested that crime drops in big cities were mostly a reflection of the crack epidemic of the '8. A trio of authors identified three major . In the early '9. 0s, these researchers proposed, the children of Crack. Gen switched to marijuana, choosing a less violent and more law- abiding lifestyle. As they did, crime rates in New York and other cities went down. Another chapter told a story of demographics: As the number of young men increases, so does crime. Unfortunately for this theory, the number of young men increased during the '9. Top: Rick Nevin, USGS, DOJ; Bottom: Rick Nevin, Guttmacher Institute, CDCThere were chapters in my tomes on the effect of prison expansion. On guns and gun control. On parole and probation. On the raw number of police officers. It seemed as if everyone had a pet theory. In 1. 99. 9, economist Steven Levitt, later famous as the coauthor of Freakonomics, teamed up with John Donohue to suggest that crime dropped because of Roe v. Wade; legalized abortion, they argued, led to fewer unwanted babies, which meant fewer maladjusted and violent young men two decades later. But there's a problem common to all of these theories: It's hard to tease out actual proof. Maybe the end of the crack epidemic contributed to a decline in inner- city crime, but then again, maybe it was really the effect of increased incarceration, more cops on the beat, broken- windows policing, and a rise in abortion rates 2. After all, they all happened at the same time. To address this problem, the field of econometrics gives researchers an enormous toolbox of sophisticated statistical techniques. But, notes statistician and conservative commentator Jim Manzi in his recent book. Uncontrolled, econometrics consistently fails to explain most of the variation in crime rates. After reviewing 1. Manzi found that only 2. So we're back to square one. More prisons might help control crime, more cops might help, and better policing might help. But the evidence is thin for any of these as the main cause. What are we missing? Experts often suggest that crime resembles an epidemic. Karl Smith, a professor of public economics and government at the University of North Carolina- Chapel Hill, has a good rule of thumb for categorizing epidemics: If it spreads along lines of communication, he says, the cause is information. If it travels along major transportation routes, the cause is microbial. If it spreads out like a fan, the cause is an insect. But if it's everywhere, all at once—as both the rise of crime in the '6. A molecule? What molecule could be responsible for a steep and sudden decline in violent crime? Well, here's one possibility: Pb(CH2. CH3)4. Rick Nevin/CDCIn 1. Rick Nevin was a consultant working for the US Department of Housing and Urban Development on the costs and benefits of removing lead paint from old houses. This has been a topic of intense study because of the growing body of research linking lead exposure in small children with a whole raft of complications later in life, including lower IQ, hyperactivity, behavioral problems, and learning disabilities. But as Nevin was working on that assignment, his client suggested they might be missing something. A recent study had suggested a link between childhood lead exposure and juvenile delinquency later on. Maybe reducing lead exposure had an effect on violent crime too? That tip took Nevin in a different direction. The biggest source of lead in the postwar era, it turns out, wasn't paint. It was leaded gasoline. And if you chart the rise and fall of atmospheric lead caused by the rise and fall of leaded gasoline consumption, you get a pretty simple upside- down U: Lead emissions from tailpipes rose steadily from the early '4. Then, as unleaded gasoline began to replace leaded gasoline, emissions plummeted. Gasoline lead may explain as much as 9. Intriguingly, violent crime rates followed the same upside- down U pattern. The only thing different was the time period: Crime rates rose dramatically in the '6. The two curves looked eerily identical, but were offset by about 2. So Nevin dove in further, digging up detailed data on lead emissions and crime rates to see if the similarity of the curves was as good as it seemed. It turned out to be even better: In a 2. PDF) he concluded that if you add a lag time of 2. America. Toddlers who ingested high levels of lead in the '4. And with that we have our molecule: tetraethyl lead, the gasoline additive invented by General Motors in the 1. As auto sales boomed after World War II, and drivers in powerful new cars increasingly asked service station attendants to . Nevin's paper was almost completely ignored, and in one sense it's easy to see why—Nevin is an economist, not a criminologist, and his paper was published in Environmental Research, not a journal with a big readership in the criminology community. What's more, a single correlation between two curves isn't all that impressive, econometrically speaking. Sales of vinyl LPs rose in the postwar period too, and then declined in the '8. Lots of things follow a pattern like that. So no matter how good the fit, if you only have a single correlation it might just be a coincidence. You need to do something more to establish causality. As it turns out, however, a few hundred miles north someone was doing just that. In the late '9. 0s, Jessica Wolpaw Reyes was a graduate student at Harvard casting around for a dissertation topic that eventually became a study she published in 2. Amherst. Although the association seemed plausible, she wanted to find out whether increased lead exposure caused increases in crime. But how? In states where consumption of leaded gasoline declined slowly, crime declined slowly. Where it declined quickly, crime declined quickly. The answer, it turned out, involved . During the '7. 0s and '8. Environmental Protection Agency rules, steadily reduced the amount of leaded gasoline used in America, but Reyes discovered that this reduction wasn't uniform. In fact, use of leaded gasoline varied widely among states, and this gave Reyes the opening she needed. If childhood lead exposure really did produce criminal behavior in adults, you'd expect that in states where consumption of leaded gasoline declined slowly, crime would decline slowly too. Conversely, in states where it declined quickly, crime would decline quickly. And that's exactly what she found. Meanwhile, Nevin had kept busy as well, and in 2. PDF). This way, he could make sure the close match he'd found between the lead curve and the crime curve wasn't just a coincidence. Sure, maybe the real culprit in the United States was something else happening at the exact same time, but what are the odds of that same something happening at several different times in several different countries? Nevin collected lead data and crime data for Australia and found a close match. And Great Britain and Finland and France and Italy and New Zealand and West Germany. Every time, the two curves fit each other astonishingly well.
