Crime Migrates to Suburbs (Wall Street Journal)

"The decline in homicides nationally has overshadowed a countertrend: rising murders in the suburbs, the communities that ring cities and have long been promoted as havens from violent crime. U.S. homicides fell sharply from 2001 to 2010, including a 16.7% drop in big cities, according to a federal Bureau of Justice Statistics study of the most recent, reported data. That is because of a host of factors, including better medical treatment for victims of violent injury and aggressive police measures in megacities like New York and Los Angeles."
