Symposium #4

outlined gangs 720

​What can street gangs tell us about radicalization and extremist groups? This symposium examines the important similarities and differences across criminal, deviant, and extremist groups. Drawing from research on street gangs, Dr. Scott Decker discusses issues such as levels of explanation,organizational structure, group process, and the increasingly important role of technology and the internet in the context of radicalization. There are points of convergences across these groups, but it is important to understand the differences between these groups. 

This presentation will review the current state of research on investigative interviewing methods. Rapport based interviewing will be discussed, particularly the effective use of rapport-building skills and how to measure rapport in an investigative interview. The presenter will also discuss the limitations of research on investigative interviewing and the importance of collaborations between scientists and practitioners in improving the use of evidence-based interviewing.
