Organized crime is considered to be a changing and flexible phenomenon. Many of the benefits of globalization such as easier and faster communication, movement of finances and international travel, have also created opportunities for transnational organized criminal groups to flourish, diversify and expand their activities. Traditional, territorial-based criminal groups have evolved or have been partially replaced by smaller and more flexible networks with branches across several jurisdictions. In the course of an investigation, victims, suspects, organized criminal groups and proceeds of crime may be located in many States. Moreover, organized crime affects all States, whether as countries of supply, transit or demand. As such, modern organized crime constitutes a global challenge that must be met with a concerted, global response.
