Bill Bratton's Approach
New York Daily News: Heather Mac Donald on how New York City Police Commissioner Bill Bratton lowered crime. An excerpt:
The idea that the police would take public, measurable responsibility for increased public safety was revolutionary. To meet that responsibility, the NYPD’s top brass started obsessively poring over crime data on a weekly, then daily, basis. Until then, crime data did not even reach the deputy commissioners until six months after the fact — far too late to actually devise strategies for protecting potential victims.
