Santos (2011), describes how analysis through the Stratified Model of Problem Solving can be based on the type or level of an incident, allowing law enforcement to tailor their response based on data analysis and response necessity. For example, data can be analyzed to determine a series of crimes, crime sprees, hot spot locations, and specific hot products or targets concerning crime. Without valuable crime data collection and analysis, proactive approaches would be minimal. Crime analysis allows for tailored responses from law enforcement to combat the specific problems in a particular area.
