"Chicago’s rough streets get all the press.
Where do you find the least crime in the city? It’s not in the richest
part of town—just the place the most police live."
"What these five places do have in common: Lots of cops (and other civil servants, including firefighters) live there. The Sun-Times
reported that, in 2005, the last year City Hall released the ZIP codes
of city workers, 71 percent of police officers lived on the Northwest
and Southwest Sides. The ZIP code that includes Mount Greenwood, for
instance, was home to 1,418 sworn officers."
