Scholars have posited there are three theories of policing globally. The first is intelligence driven where the police rely on intelligence and information gathering, data, trends, informants and surveillance to detect and prevent crime and catch criminals. This model has proven vital especially when dealing with organised crimes such as terrorism, drug and human trafficking.
The second model is regime-based policing. In this model, the police exist to serve and protect the interests of those in power. Quite often, the police leadership is handpicked by the president and can be fired at any time. Under this model, those perceived a threat to the political establishment are quickly neutralised at the behest of the ruling class. The political establishment looks the other way when the police extort and brutalise citizens. Regime-based policing does not recognise the rights and legitimacy of the citizenry, especially when they differ with the opinion of the State.
