The New York City Police Department (NYPD) has primary responsibility for law enforcement and investigation within New York City.
The New York City Transit Police and housing police were fully integrated into the NYPD 1995; some new police officers are randomly assigned to the Transit and Housing units.
The Compstat[?] program, introduced under then-Commissioner Bill Bratton in the 1990s, uses statistics about crime rates and arrests to evaluate police precincts and commands. As of June 2003, there are charges that the statistics have been falsified to make the department look better.
The size of the force has fluctuated, depending on crime rates, politics, and available funding.
