the truth: GIS not cost-effective for police work (Score 1)

One reason is because police officers "on the ground" know where the "hot" areas are long before the criminal intelligence group runs statistics.

Also, GIS systems that use maps always have outdated and incorrect information: the map says a warehouse is at a location X but the officers from the area remind you that the warehouse was replaced by an apartment complex 3 years ago.

I did studies for a major metropolitan police agency for years, specializing in GIS. There was never a case where purchase of a GIS system could be justified. Nevertheless no less than 3 such systems were purchased by our department in an attempt to find a use. These costed millions of $; they're sitting in the police IT machine room unused today!
