This text looks at the various strategies and techniques of interviewing and interrogating witnesses, victims and suspects. Topics include: types of interviews, crime scene considerations, deciding to interrogate, The Right To Remain Silent, interrogation techniques, interrogation props, defensive measures, recording the confession, etc. Gilbert takes a unique "offender-based" strategy that focuses on the offender and the witness type in order to create a more successful process. Rather than strictly examining the practicalities, including interrogation setting, demeanor or plan, Gilbert focuses on the "why" of offender confessions and witness communication.
