This list of topics (questions) goes on and on and focuses on how you appear while on the witness stand, and how to understand and exercise your rights while testifying. How you deal with these scenarios determines the level of trust the jury is willing to place in you as an expert witness.

 As you can see, these questions have nothing to do with your expertise. Don’t worry, that comes later in this webinar.

Introduction to the speaker and expectations of students.

9:30 AM-11:00 AM  CST

The role of an expert witness in a trial?   

Below are just a few of the topics that we will cover, and they apply to all forensic expert witnesses, regardless of your discipline. Ron will clearly show you that your forensic discipline in court has much more in common with other disciplines than differences. Most agencies that do have expert witness training programs focus on the technical questions that the witness might be asked when there are so many things that a new witness needs to know just to get through the first few minutes. This is where the expert witness begins to gain the “forensic trust” of the jury. Let’s start there.
