In this lecture I will talk about two new approaches for interrogation. The first approach is the Strategic Use of Evidence (SUE) technique. Broadly speaking, the SUE technique gives guidance with respect to how to most effectively use the critical background information when interrogating suspects. I will draw attention to one particular aspect of the SUE-technique; how to strategically disclose different pieces of information. The second approach is the Scharff technique and this technique is for collecting human intelligence; it is used to gather information from sources, suspects and detainees. I will introduce the concept elicitation and I will give examples of specific tactics that can be used to gently draw out secret information. The Scharff technique is inspired by approach invented by Hanns Joachim Scharff, who worked as an interrogator for the German Luftwaffe during WWII. Today the Scharff technique is taught to elite units around the world, such as the NYPD, LAPD, the FBI and MI5.
