The government alone cannot provide security that will satisfy those who need it most, because they must have more than others. Therefore, the government tolerates security operated on a commercial basis, as well as voluntary self-protection. Private security has increasingly become a competitor to the government, particularly in societies that have a privatization mentality and are undergoing processes of privatization of property once held in common. However, the government has to provide adequate control and regulate the power of private security businesses and private detectives, which both operate on the profit motive. Central issues are the delimitation of domains between the government police and private security, competencies, and the prevention of unlawful activities that benefit private security, which either purchases or maintains surveillance and security services. Voluntary self-protection also has much to offer, although it has not become established in Slovenia despite its previous high level. Slovenia should integrate the entire development of government and private security, including government-regulated self-protection, into a comprehensive concept of crime and delinquency policy. 9 references (Author abstract modified)
