Hanna Rosin, writing in The Atlantic, examines the new American Murder Mystery:
Falling crime rates have been one of the great American success stories of the past 15 years. New York and Los Angeles, once the twin capitals of violent crime, have calmed down significantly, as have most other big cities. Criminologists still debate why: the crack war petered out, new policing tactics worked, the economy improved for a long spell. Whatever the alchemy, crime in New York, for instance, is now so low that local prison guards are worried about unemployment.Lately, though, a new and unexpected pattern has emerged, taking criminologists by surprise. While crime rates in large cities stayed flat, homicide rates in many midsize cities (with populations of between 500,000 and 1 million) began increasing, sometimes by as much as 20percent a year. In 2006, the Police Executive Research Forum, a national police group surveying cities from coast to coast, concluded in a report called “A Gathering Storm” that this might represent “the front end … of an epidemic of violence not seen for years.” The leaders of the group, which is made up of police chiefs and sheriffs, theorized about what might be spurring the latest crime wave: the spread of gangs, the masses of offenders coming out of prison, methamphetamines. But mostly they puzzled over the bleak new landscape. According to FBI data, America’s most dangerous spots are now places where Martin Scorsese would never think of staging a shoot-out — Florence, South Carolina; Charlotte-Mecklenburg, North Carolina; Kansas City, Missouri; Reading, Pennsylvania; Orlando, Florida; Memphis, Tennessee.
Richard Janikowski, a criminologist with the University of Memphis, started mapping the rise in crime there:
When his map was complete, a clear if strangely shaped pattern emerged: Wait a minute, he recalled thinking. I see this bunny rabbit coming up. People are going to accuse me of being on shrooms! The inner city, where crime used to be concentrated, was now clean. But everywhere else looked much worse: arrests had skyrocketed along two corridors north and west of the central city (the bunny rabbit’s ears) and along one in the southeast (the tail). Hot spots had proliferated since the mid-1990s, and little islands of crime had sprung up where none had existed before, dotting the map all around the city.Janikowski might not have managed to pinpoint the cause of this pattern if he hadn’t been married to Phyllis Betts, a housing expert at the University of Memphis. Betts and Janikowski have two dogs, three cats, and no kids; they both tend to bring their work home with them. Betts had been evaluating the impact of one of the city government’s most ambitious initiatives: the demolition of the city’s public-housing projects, as part of a nationwide experiment to free the poor from the destructive effects of concentrated poverty. Memphis demolished its first project in 1997. The city gave former residents federal “Section8” rent-subsidy vouchers and encouraged them to move out to new neighborhoods. Two more waves of demolition followed over the next nine years, dispersing tens of thousands of poor people into the wider metro community.
If police departments are usually stingy with their information, housing departments are even more so. Getting addresses of Section 8 holders is difficult, because the departments want to protect the residents’ privacy. Betts, however, helps the city track where the former residents of public housing have moved. Over time, she and Janikowski realized that they were doing their fieldwork in the same neighborhoods.
About six months ago, they decided to put a hunch to the test. Janikowski merged his computer map of crime patterns with Betts’s map of Section8 rentals. Where Janikowski saw a bunny rabbit, Betts saw a sideways horseshoe (“He has a better imagination,” she said). Otherwise, the match was near-perfect. On the merged map, dense violent-crime areas are shaded dark blue, and Section8 addresses are represented by little red dots. All of the dark-blue areas are covered in little red dots, like bursts of gunfire. The rest of the city has almost no dots.
Betts remembers her discomfort as she looked at the map. The couple had been musing about the connection for months, but they were amazed — and deflated — to see how perfectly the two data sets fit together. She knew right away that this would be a “hard thing to say or write.” Nobody in the antipoverty community and nobody in city leadership was going to welcome the news that the noble experiment that they’d been engaged in for the past decade had been bringing the city down, in ways they’d never expected. But the connection was too obvious to ignore, and Betts and Janikowski figured that the same thing must be happening all around the country. Eventually, they thought, they’d find other researchers who connected the dots the way they had, and then maybe they could get city leaders, and even national leaders, to listen.
