This chapter explores issues in undertaking policing research, especially regarding power dynamics in knowledge production as they relate to research and researchers in the Global North and South. Knowledge on policing is dominated by scholars from the Global North. Increasingly, there is attention being paid to whether research is ethical, not only whether participants give informed consent, etc, but whether researchers have the right to study people and phenomena of any sort in the Global South. The chapter provides an overview of some perspectives of researcher positionalities, and their advantages and limitations when conducting research on potentially sensitive topics, such as policing, in one-party communist states, in this case, Vietnam. To better elucidate the practical and methodological implications of researcher positionality, three brief case studies are provided. The chapter concludes by noting that research is a collective effort, notwithstanding the constraints inherent within some researcher positions, while enabling advantages in others, and the impact that different positions have on the production of policing knowledge in relation to Vietnam.
