Terrorism and National Security: Student Investigative File is a uniquely immersive educational experience that provides students with terrorism and national security-related fact patterns and hypothetical, fluid scenarios while challenging them to assume the role of an investigator. As the investigator, students examine the facts, build a case, and plan court-related outcomes within this affordable text/workbook with accompanying active learning materials. To complement the fact patterns, the text includes crime scene illustrations, worksheets, and example legal documentation. Students receive investigative updates throughout each section to help them organize and build their case while also learning professional record-keeping and report writing skills. With proper investigative techniques and application of the law, their investigation culminates in a hypothetical resolution and charge. This text helps students foster their knowledge of classifications and designations of terrorism, investigative techniques, legal considerations, examples of hate crimes, research of relevant case material, investigations of a group versus individual offenders, and more. Terrorism and National Security is part of From the Files of Fanelli and Moscato: An Investigative Criminal Justice Series, a collection of scenario-based textbooks and active learning materials that help students cultivate critical thinking and investigative skills while applying their knowledge of key criminal justice principles, techniques, and theories.
