Secondary research in CJS can help enhance a data driven criminal justice system in the following ways:

1. Trace the evolution of existing practices within the justice system. This especially helps with sharing of new found perceptions and implications of well established theoretical explanations of criminal incidences and criminal behaviour.
2. Acknowledge universality of human behaviour and thereby help develop an increased comprehension of how to adopt best practices across cultures and communities.
3. Transcend the day to day silos of information between each unit of the justice system and present a more holistic picture of the justice system as one complete unit. Every faction of the justice system is over-worked and under-staffed. Even with the best intentions in mind, it is not humanly possible to dedicate as much time as needed in information sharing across the departments. This is where a Criminologist or a Researcher in the field of Criminology can step in and get the long-due work done in targeted, strategic research in CJS.
4. Amplify faith, hope and resilience for victims and witnesses in their healing journey. It takes a great deal of effort to zoom out of the myopic view we tend to get about our own life incidences, even when we are not a victim of or witness to a crime. It is hard to imagine what hope could even mean to a victim of crime or what faith could mean to a witness. Shared knowledge of similar criminal incidences from around the globe and across different cultural communities can provide a strong foundation for rebuilding trust in the human community.
5. Create a strong multidisciplinary evidence based database for criminal justice professionals to refer to for effective tactical and strategic operations. This is a debatable thought, and there is no easy solution. Building comprehensive databases within the justice systems pose immense threats, and the risks could be unimaginable with the present evolution of artifical intelligence, and augmented and virtual realities. However, the irony is that the higher the risks, the more pertinent it becomes to take the initiative.
