Ethics of Duty and Crime Prevention: Practical Applications of Kantian Philosophy in Tanzania

Since attaining independence in 1961, Tanzania has enjoyed relative peace and stability, with comparatively low crime rates within the East African region. However, from the early 1980s onward, the country witnessed a notable increase in criminal activities, including mugging, bag snatching, vehicle assaults, armed robbery, and burglary. This paper examines the practical relevance of Kantian moral philosophy—specifically the ethics of duty—in addressing crime prevention in Tanzania. Kantian ethics asserts that moral actions stem not from social conventions or personal desires, but from rational adherence to duty. Accordingly, crime prevention may be more effectively pursued when individuals act from a rational commitment to moral law, rather than from fear of punishment or pursuit of personal gain. The study employs a qualitative approach, drawing data from books, government documents, policy papers, development plans, legal statutes, internet sources, police records, and historical materials. Findings indicate a widespread lack of public ethical awareness concerning crime and its prevention. The paper concludes that incorporating Kantian ethics into national policies, civic education, and legal frameworks can serve as a morally grounded strategy for reducing crime and promoting social responsibility in Tanzania.
