The Cameroon Public service is a blend of the moral and cultural values that were inherited in British and French systems of administration along with the desire put in by the different administering authorities to cope with the demands of time. Unfortunately, this blend even in the era of modern technology with improved tools of communication has not completely destroyed the ligaments of financial crimes and scandals that have encumbered this department. Going by reachable evidences, in the heat of economic crises that warranted the introduction of broad based structural adjustment Programmes, Cameroon ranked twice as most corrupt country in the world. Again, most of the top officials (ministers and directors) that have served the different departments of the public service have been judged and sentenced for differential durations in prisons due to financial crimes.The questions that beg for convincing answers are; why is the Cameroon public service department still bedevilled by financial crimes inspite of the measures put in place to assure transparency? What are these crimes and what is their impact on national and international dealings? From primary and secondary sources complimented with statistical and oral interviews, this paper argues that the near absence of blueprint etiquettes along with administrative lapses is at the root of these financial crimes. It uses the way accountability was assured in the management of Southern/West Cameroon budget as model to argue that; with a determined will churned from endearing etiquettes, the financial crimes alive in the Cameroon public service can be reduce to the barest minimum or at best, eliminated. It posits that in an era of modern technology, moral etiquettes that express themselves in an astute art of private and public righteousness of financial management is required of state authorities. By so doing, it makes a claim which is not only valid for Cameroon but also for every state and institution suffocating under the spell of financial crimes that, much can be redeemed using the model provided.
