The Balkans host sufficiently strong organized criminal groups. Strong smuggling channels developed in the western Balkans that served to avoid the imposed embargo during past conflicts are still being intensely exploited by these organised crime groups. They have the tendency to combine several types of smuggled commodities when exploiting these channels. The criminal groups exploit developing economies, which require high infusions of capital, in order to launder money obtained from illegal activities. Since many organised crime groups have a large portfolio of crimes, the horizontal cooperation of different specialised units or agencies at the national level should be taken into consideration from the early stages of investigations. Law enforcement agencies should improve their logistical capacities and efficiently manage them so as to keep pace with the technical and logistical capacities of organised crime groups. The specialization and capacities for technical expertise of law enforcement agencies should be considered a priority and implemented through the proper management of human resources and adequate training programmes.
