Founding Members

All good ideas start with good people.  In our case, the American Society of Evidence-Based Policing was started by a small group of like-minded policing folks. We are all active in law enforcement as Police Officers, Sergeants, Lieutenants or Crime Analysts but collectively, we felt it was time for a change.  Our bios are below but you’ll probably find that we’re just like you… we want to make a difference in our profession and encourage you to join us.

Additionally, he supervised for the Bureau’s Domestic Violence Reduction Unit and worked to implement one of the nation’s first automated actuarial risk assessment systems.  This system was used to conduct risk-based case assignment aimed at targeting domestic offenders with the highest risk of recidivism for additional follow-up.

Sergeant Stewart has an undergraduate degree in Psychology from Lewis and Clark College and a master’s degree in science from Portland State University’s Criminology and Criminal Justice Program.  His studies included the use of geographic information systems, statistics, research methods and data analysis.  His culminating project for the master’s degree consisted of training a group of college students to code police use of force cases for both traditional variables (force factor) and also for constitutional factors such as governmental interest and level of control achieved prior to the application of force.  He then conducted checks on inter-rater reliability to demonstrate the feasibility of reliably coding factors related to constitutionality from administrative records of police use of force.

Sergeant Stewart has presented at a number of academic and professional police conferences such as the International Association of Chiefs of Police, the International Association of Crime Analysts and the American Society of Criminology.  His research has touched on issues such as police use of force, the use of risk assessment tools to improve case assignment, the impact of stereotype threat on citizen/police interactions and exploring alternate patrol strategies aimed at simultaneously maximizing police legitimacy and crime reduction. He has also trained or consulted for police agencies from the United States, Canada, Bangladesh, Mexico and the Ukraine.
