This book assessed the threat posed by transnational organized crime such as global drug trafficking, racketeering, fraud, human trafficking, smuggling, cyber-crimes, money laundering and terrorist financing etc. For many developing countries, powerful transnational criminal networks represent a direct threat to the state itself. Moreover, the situation has been exaggerated by the emergence of globalization and advanced information and communications technology, which helped to aid the criminals in escaping at the international community. The book is very important for law enforcement agencies, intelligence agencies, students and other institutions that are responsible for fighting financial crimes. This book-length report addresses techniques used to track down criminals who are highly motivated, trained, organized, disciplined and well funded and it concludes with recommendations for steps to be taken at the national, regional, and international levels to counter transnational organized crime.
