This paper discusses research on human traffickers (i.e. perpetrators of the crime of human trafficking) and how a clearer picture of how traffickers operate can be used in the development of criminal justice and social welfare responses to human trafficking. This study discusses some of the difficulties or limitations involved in understanding traffickers and trafficking operations through the lens of trafficked persons and their individual trafficking experiences and what that means for the development of policies, strategies and interventions in combating human trafficking.
