In the framework of coercive political systems, public security subsystems are distinguished by the establishment of agendas focused on crime prevention, justice delivery and social rehabilitation. However, the relationship between rulers and ruled has been disrupted as security sub-systems have turned to private security strategies such as video surveillance and the hiring of bodyguards. In another sense, public security has led to the self-defence of communities oriented towards self-management and self-governance of relations between civil society and those who govern.
