Cop Land: NYPD Officers cannot live in New Jersey
The whole premise of Cop Land was based on the erroneous proposition that a bunch of disillusioned NYPD Officers set up a community of cops across the Hudson River in the fictious town of Garrison, New Jersey with the full knowledge of the Police Department.
NYPD Officers cannot live outside of the State of New York. They are required by law to reside within in the New York State counties of New York, Kings, Richmond, Queens, Bronx, Nassau, Suffolk, Westchester, Putnam, Rockland, and Orange.
If ever there was an actual "Cop Land", I would have to say it was located in the Town of Pearl River, in Rockland County, New York. Hundreds of New York City Police Officers, in addition to Firefighters and other civil service employees, started moving into this small community beginning in the late 1960's and continuing into the '70's and '80's.
