Crime Analysis Collection and analysis of data pertaining to a criminal incident, offender and target. Crime Analysis will only be as good as the data collected in the process. In order to understand the data collected, we have to understand the causes of it. Sort of a street-level criminology if you will.

Three essential citeria for crime analysis 1) Timeliness – does the data show that there is currently a problem or is it a problem of the past. 2) Relevancy – do the measures used to collect the data reflect what is intended. 3) Reliability – would the same data interpreted by different people at different times lead to the same conclusion.

Technologies Used to track data CAD – Computer aided dispatching. Used to dispatch calls for police service. This is usually the first point of data entry.
