Analyzes the separate roles and functions of the police and the military in the context of the current security environment in the Caribbean, which now includes such diverse factors as trans-national organized crime, corruption, links between politics and crime, natural disasters, oil dependency, high levels of public debt and the chronic marginalization of large sectors of the population. This paper argues that rapidly evolving challenges require that the roles, functions and training of the police and the military be kept separate and distinct, and that the policy community needs to understand why the purpose and architecture of the training has to be appropriate for the different missions of the respective organizations.
