Witness Resistance Strategies for the Defense Investigator
On-Demand CourseCourse Overview
Reluctant witnesses can make or break a defense case. This course teaches private investigators how to diagnose the real reason a witness is holding back, classify them into one of seven resistance types, and apply the right strategy to get truthful testimony. Using the PILA Method — Locate & Profile, Diagnose, Classify, Plan, Engage, and Document — and a real-world case study, you'll learn how to locate and approach witnesses, build rapport under difficult conditions, and document interviews and refusals in a way that protects the case. Taught by Catherine Flowers.
