A scientist's research challenges the "broken windows" theory.
"In a landmark 1997 paper that he wrote with colleagues in the journal Science, and in a subsequent study in The American Journal of Sociology, Dr. Earls reported that most major crimes were linked not to "broken windows" but to two other neighborhood variables: concentrated poverty and what he calls, with an unfortunate instinct for the dry and off-putting language of social science, collective efficacy...rather than focusing on arresting squeegee men and graffiti scrawlers, local governments should support the development of cooperative efforts in low-income neighborhoods by encouraging neighbors to meet and work together. Indeed, cities that sow community gardens, he said, may reap a harvest of not only kale and tomatoes, but safer neighborhoods and healthier children."
