  This paper proposes a systems theory approach to the modeling of onset and
evolution of criminality in a territory, which aims at capturing the complexity
features of social systems. Complexity is related to the fact that individuals
have the ability to develop specific heterogeneously distributed strategies,
which depend also on those expressed by the other individuals. The modeling is
developed by methods of generalized kinetic theory where interactions and
decisional processes are modeled by theoretical tools of stochastic game
theory.
