The late 20th and early 21st centuries have seen a phenomenal growth in society's use of information technology. Criminals, including terrorists and terrorist organizations, have also adopted information technologies. Information technologies are used to enhance the efficiency, productivity, and effectiveness of terrorist activities and offenses. Investigating terrorist use of information technologies creates a number of challenges for law enforcement officials. While some of the challenges are encountered during conventional criminal investigations, terrorist investigations also present unique challenges. Through content and typological analysis, this study examined open source information to identify, categorize and propose a model of these challenges. Four primary categories were identified: technology, methodology, legal, and administration and human resources challenges.
It is the purpose of this thesis to examine systematically the theories of selected sociologists and anthropologists with the end in view of determining whether or not or to what degree the various dichotomies are valid and useful. In addition to specific criticisms of doctrines peculiar to individual theorists, an attempt will be made to answer the following questions: What are the theoretical sources from which the dichotomies of types of social life in modern sociological and anthropological theory are derived? Are the dichotomies based upon legitimate contrasts which can be demonstrated empirically? To what extent do the value orientations of the theorists bias their results? How valuable are the dichotomies as guides to empirical investigation? To what extent do the dichotomous theories contribute to an understanding of the causes and directions of social change?
