The article “What Have We Learned from Offender Profiling” by Bryanna Fox investigates the tools used by the academics, law enforcement, consultants and the psychologists in the identification of major behavioral, demographic and personality features of offenders.  The identification of behaviours and personality of offenders is based on a meta-analysis of crime scenes in over four decades to identify the current state and evolution of offender profiling. Therefore, the 40 years meta-analysis provides a linkage between single offenders and the accuracy of crimes which helps in proving that profilers tend to be ‘better than bartenders’ by predicting their traits.  According to the author, conducting a scientific and systematic evaluation for offender profiling is essential as the study is famous for criminology and psychology research.  The offender profiling study is based on various journal articles which explore the increase in the number of offender profiling for the last few decades.  Based on the studies analysis of case linkages and reviews of OP publications, the current aim of this study aims at enhancing a better understanding of the methodologies, data, approaches, building and replicating the analysis into different approaches to help readers gain a comprehensive view on current state of offenders profiling.  In a nutshell, the OP is a topic for many reports and journal articles as well as an investigative technique that enhances scientific assessing the existence of profiles.
