2017 NACOLE Webinar Series

Assessing the Credibility of Witnesses

Join us Thursday, May 18, 2017, 2:00PM EDT*, as we welcome Jayson Wechter, a veteran former investigator at the San Francisco Department of Police Accountability (DPA), and John Alden, an attorney at the San Francisco Department of Police Accountability, to discuss how to conduct credibility assessments.

This one-hour webinar will cover the basic concepts used to assess the credibility of complainants, witnesses and law enforcement officers. It will describe how to systematically evaluate and analyze contradictory accounts of an incident and how to conduct thorough interviews that allow an evaluation of a witness’ credibility. It will discuss relevant factors to consider in making credibility assessments, including an individual’s ability to perceive, recall and describe an event; conscious or unconscious bias; motivation; attitude and character; demeanor; consistency of statements; and consistency with other evidence.
