The Perfect Storm?

From the NYT:

New York, of course, has over the last 15 years seen an extraordinary drop in crime, from the most serious to the mildly irritating. But across all those years, economists and sociologists have debated how much of the success was attributable to new trends in policing and how much to other factors, including a robust economy.

Now, if the dire predictions of economic hardship prove accurate, the city may be poised to find out in a real-time experiment. And it will have to conduct that experiment with thousands fewer police officers than it had in 2001.
