The paper describes the organized criminal, and the fight against organized
crime from a behavioural point of view. The author considers the organized
criminal a crime-entrepreneur who has to operate in an enduring violent en
trepreneurial landscape in which he has to cope with the problem of social
information management. The article described how the police can add a soci
al psychological approach to the traditional investigative methods. It prov
ides some experience obtained in the Netherlands in which the psychologist
assisted the crime squad during the investigation, trial preparation and tr
ial. It argues in favour of a more analytical, hypothesis testing method in
which the behavioural scientist is integrated in the operational organized
crime squad instead of acting as an outside consultant.
