Bringing 37 years of academic and professional experience to one of the toughest areas of civil litigation.

Since the turmoil in Ferguson, Missouri in 2014, the need for knowledgeable and qualified expert witnesses in the areas of police practices and use of force has become more important than ever, both to insure justice for the victims of excessive force, and to protect dedicated police officers who act appropriately and within the law. Having served as the Plaintiff's expert in essentially every police shooting that occurred in St. Louis during the unrest in Ferguson, as well as a number that have happened since, I have experienced firsthand the impact these cases can have on a community. I recognize the importance of my task, and the need to pursue a truthful and objective analysis of the facts. 

Services Offered

When I complete a case analysis, I typically submit a final report that includes each of the following sections. I can also perform any one of them individually. For example, I have been contracted in the past to assist only in a Daubert motion.

1. Incident scene reconstruction

2. Force analysis

3. Evaluation of police investigation

4. Evaluation of opposing expert's report (with Daubert/Frye affidavit if desired)

Free Case Review

I do not charge for an initial case review. Before agreeing to work a case,  I review the available documents, videos, and evidence to determine if my qualifications and expertise are sufficient to offer an expert opinion on the matter in question. If I agree to work a case after my initial review, then a contract will be forwarded to the appropriate attorney. I do not require a retainer.

I will be attending this training in August 2020 at St. Louis University. This is will add a new dimension to my areas of expertise and testimony. A fuller description will be added soon.

The Michael Brown Report 06/21/2017

I served as the expert witness in this case on behalf of the Brown family. I completed an independent investigation and filed with the Court an Expert Opinion Report detailing what the evidence shows actually happened that day in Ferguson. While the terms of the settlement were sealed by the Court, my report was not. You may download a copy by clicking on the PDF link below...

About Me...

In addition to my 37 years in law enforcement, first as a deputy sheriff, and for 25 years as a special agent for the State of Illinois, I was also privileged to teach at one the nation's top research institutions, Washington University in St. Louis. At WU I taught a number of courses in the Forensic Psychology program, an undergraduate certificate program that I personally developed from the ground up. The courses I taught included forensic psychology, criminology, correctional theory and practices, and crisis intervention, among others. Additionally, I have authored four widely used textbooks, two of which deal at length with the subject of deadly force by the police. You can find my books, as well as my CV, under the link above. 

New Documentary

A new documentary has been released on the case of Dontre Hamilton in Milwaukee, WI. I had the opportunity to serve as the expert witness on this case. Dontre was a young man suffering from mental illness who was shot and killed by a Milwaukee police officer. His only crime was sleeping in a city park.



If you've ever been on the plaintiff's side of an excessive force case, you no doubt were confronted with something called the "reactionary gap." Pro-police experts routinely use it to help justify an officer's actions. The article provides a strategy for challenging the use of this piece of pseudoscience.


PERCEPTUAL DISTORTION (But whose perception is being distorted?).

And informative article about one of the popular arguments used by pro-police experts to help justify just about any questionable use of force.



A research project I recently completed to determine how often when an officer shoots a fleeing suspect in the back after reaching for their waistband a weapon is actually found on their person.
