The Strategic Use of Evidence is a planned questioning approach and maybe a disclosure technique. It is NOT simply a late disclosure or a late dump of evidence. Join SUE co-creator Dr. Maria Hartwig and Capt. Christian Cory (ret.) as they discuss the research on deception, the strengths of the Strategic Use of Evidence (SUE) technique, and how to put it into practice.

Better Questioning Objectives
SUE questioning is built around your evidence. Your objective is to elicit uncontaminated statements you can corroborate, or to explore contradictions between what someone says and what the evidence shows. You’ll see how to plan your questions around that objective.

Evidence Disclosure...Maybe?
What is the purpose of disclosure? Who said you have to disclose? Some of the bad information out there is that there will absolutely be disclosure; however, isn't an uncontaminated, corroborated statement a gold standard?
