It is necessary, too, while maintaining that focus, to ensure emerging trends in organised crime are analysed and monitored in order that effective legal instruments and operational policies are developed in a coherent and co-ordinated strategy. Anticipating trends is becoming more and more important as organised criminal gangs respond to new opportunities nationally and internationally. This underlines that intelligence led policy, on which I spoke to the commissioner at some length recently, and international co-operation should be important strategies for responding to serious criminal activity.
