Jurnal Kriminologi Indonesia Vol. 4 No. I September 2005 : 1 - 6 1 TERRORISM AND INVESTIGATION STRATEGIES Muhammad Mustofa Abstract This paper discussed that, for successful implementation of the strategies in investigating terrorism, besides requiring professional skilled investigators, there are some additional requirements that need to be fulfilled. Effective and long term prevention of terrorism should be directed towards producing good social welfare and to minimize every condition that may be conducive to the emergence of terrorism, such as discrimination and marginalization. Key Words: terror, terrorism, investigation strategies Introduction Terrorism is not a new problem, because it has been threatening free society for decades, but since the 11 September 2001 terrorism attacks on the USA, terrorism has become the most feared type of transnational crime, which has attracted the special attention of law enforcement agencies (local as well international), and scholars of various disciplines. All the attention is directed to the search for the most effective measures in combating international terrorism. Furthermore, terrorism threats and attacks are not only against industrial countries, but also against developing countries. Indonesia, for instance, as one of the developing countries in Asia has experienced international terrorism attacks, following the 11 September attacks. Authorities suspect the Bali bombing in 2002, the J.W. Marriott Hotel bombing in 2003, and the Australian Embassy bombing in 2004 involved international terrorist groups. Even though most of the Bali bombing terrorist members who have been arrested and prosecuted by the Indonesian law enforcement agency are Indonesian, their attacks posses international dimension in terms of their net-works, victims and targets. As terrorism has become serious threat to free society, it needs effective strategies in investigating incidents of terrorism. Investigation, according to Myren and Garcia: “…is a process that fits into a context of determination of fact for decision- making purposes. It is the activity that produces the facts on which our decisions are based. It is an all pervasive function, central in both our personal and professional affairs…” (Myren, Garcia, 1989:3)
