This study argues that preservation of internal security of Namibia should not be the primary responsibility of only the Namibian Police Force (NamPol). The issue of security has been the subject of interest throughout human existence and still reserves its principal occupation in the public domain. However, the challenges of insecurities and increased threats to human existence domestically and globally have triggered incessantly renewed security inquiry by scholars, security practitioners, politicians and public administrators. The study employed a qualitative approach; interviews were used to purposively collect data from 20 participants which comprised of the heads of directorates, the regional commanders in the Namibian Police Force, Legal Assistance Centre, NamRights, Namibian Defence Force, Namibian Correctional Service and Windhoek Municipal Police. The data was analysed using thematic analysis, which led to the development of the Framework for Performing Internal Security [FPIS] model. The findings indicate that due to the nature of factors linked to insecurities, such as technology, porous borders, political factors, environmental factors, inequality, poverty, unemployment and lack of provision for essential services, the Namibian police alone cannot preserve internal security effectively. As such, the study recommends that constitutional amendments to incorporate other stakeholders in the preservation Namibia’s internal security.
