Franklin Zimring quoted in The New York Times, June 28, 2012
In an interview Wednesday, Mr. Zimring said his research found that the 80 percent decrease in those four crimes reported by the department from 1990 to 2009 was “real.” He said that there was always “some underreporting, and there is some downgrading in every police force that I know of,” but that his research showed that any manipulation was too minuscule to significantly affect the department’s crime statistics.
