Registration Process Register

The interrogation of suspects is both a necessary and critical stage of the criminal investigative process. The decision to move on from an interview to an interrogation of a suspect will hinge on a combination of factors, including the amount and strength of available evidence and the investigator’s level of confidence in that evidence. When an investigation advances to suspect interrogation, officers require effective interrogation techniques to obtain the information of interest.

Interrogation Techniques is the fourth and final course in the Interview & Interrogation Series. It introduces the strategies and techniques associated with Persuasion-based, Information-gathering, and Evidence-based approaches to interrogation and employs a series of short videos to demonstrate how these techniques can be employed.
