Measuring crime in and of itself implies at least three articles of faith: (1) There is value in the standardization of what is being measured; (2) Mathematics makes it possible to recognize and specify differences in exceptionally precise terms; and (3) What is measured is worth measuring. The article presents three specific solutions to three general problems: Problem 1 -- Measuring Police Competence: the consequences of a good definition; Measuring What Ought Not To Be Happening: the systematic and standardized use and distribution of calls for service and dispatch data; and Measuring What the Police Are Doing About What Ought Not To Be Happening: surveying consumers. Problem 2 -- Measuring Police Skill: good policing yields good measurement. Problem 3 -- Measuring Police Integrity: overcoming the fear of finding out what you want to know.
