Terrorism, Political Extremism, and Crime and Criminal Justice

Abstract

This review focuses on terrorism and extremist crimes, including ideologically motivated hate crimes. Research on these topics has become more rigorous in recent decades, and more scholars have engaged in original data collection. Our assessment found a burgeoning literature that increasingly includes the application of integrated theories, but gaps remain as few studies examine life-course and critical approaches. Our review of the policing of terrorism found a limited evidence base for counterterrorism initiatives. We also found that court/sentencing issues are understudied. We suggest improving data quality in these areas by creating a national data collection protocol on these crimes, enhancing the rigor of offender and victim self-report studies, and requiring more transparency from open-source research efforts. We propose that government agencies fund rigorous evaluations of policing strategies in the terrorism context. Finally, it is hoped that increased access to federal court documents will lead to more scholarly attention on sentencing issues.
