New York City Police Department
The New York Police Department's Street Crime Unit (motto: "We Own The Night") was a 300+ member plain clothes unit for reducing crime that became well known after the 1999 killing of Amadou Diallo.  The four officers who did the killing were all members of the unit. The unit was ended in 2002 because of the Diallo shooting.  The unit's last leader was Inspector Bruce H. Smolka, who was later made Assistant Chief. The Street Crime Unit is now replaced by local precinct Anti-Crime Units.
