This class introduces the tools and methods used by investigators working proactive cases, with an emphasis on narcotics and vice investigations. The course shows students how to plan and steer an investigation from the moment of identifying targets to litigation and conviction. Students will learn about the tools available, how to use them effectively, where to go for help, and legal issues. Students will go from the passive/reactive role of observing a case unfold to the commanding role of a lead investigator. They will find out how to build a case with a group or task force, using informants and working with prosecutors, paralegals, forensic accountants, analysts, and other professionals.
