Our Team
History
In the 1980s, two California police officers, Rich Wemmer and Ed Deuel, were deeply concerned with the safety and welfare of law enforcement personnel. Nationwide, more and more peace officers were being assaulted, and far too many were losing their lives on and off-duty. Individually, they recognized that police work was becoming more demanding, difficult and extremely dangerous. Although initially unknown to each other, their passion for preparing officers to face that “Moment in Time” was a common theme that would eventually unite them.
In the 1990s, Ed and Rich served as long-standing members of the California Peace Officer Standards and Training’s (POST) Law Enforcement Officers Killed and Assaulted (LEOKA) Advisory Committee. This committee studied numerous critical incidents where California law enforcement personnel were killed in-the-line of duty, both on and off-duty, due to accidental, felonious, and other causal factors. Subsequently, they met Marcus Young who joined the CA LEOKA Advisory Committee. Marcus shared Ed and Rich’s passion for officer safety and they worked together in making officer safety videos, presenting training, and publishing findings on peace officer death and safety guidelines.
In 2007, Ed Deuel and Rich Wemmer decided to unify their efforts and law enforcement knowledge to form the Peace Officer Safety Institute. Combining over 70-years of practical law enforcement experience, including their numerous examinations of peace officer accidental deaths, assaults and murders, they developed a Center to research, and to train peace officers at all ranks to make accurate assessments and timely decisions in tactical situations.
In 2018, Ed retired from the Peace Officer Safety Institute, agreeing to serve as a consultant to the center’s efforts. Marcus joined with Rich to continue the goals and work. Rich and Marcus publish articles, make training presentations, and work with law enforcement agencies. Their efforts are directed toward enhancing public safety and making the men and women in law enforcement more effective and safer in these difficult, demanding, and dangerous times.
Purpose
Today, the communities we protect and serve demand that officers possess specialized law enforcement knowledge and skills and perform without error or impropriety. While there are many who use their skills effectively and safely in predictable and stable situations, far fewer peace officers can immediately and properly adapt to chaotic, rapidly changing, and unanticipated conditions without performance errors. Furthermore, such lapses in police performance can endanger public safety.
Whenever an officer is confronted with an unexpected threat, there are crucial tasks that must be performed without delay or error. The officer must immediately recognize the new threat, appraise the threat’s imminence and severity, select a different tactical option, and respond in a legal, proper and safe manner within “real-time”.
Historically, post critical incident liability reviews determined if a peace officer correctly performed these tasks. When the officer’s actions were found to be improper, consequences for the municipality, agency and officer occurred. These included discipline, civil and criminal liability, and often resulted in damage to the peace officer’s personal health and welfare.
The Center offers a wide variety of activities and services to make peace officers safer and to achieve our goal of preventing peace officer accidental deaths, assaults and murders. We strongly believe these services will significantly reduce the catastrophic financial and personal impact of critical events on the community, the law enforcement agency, and the officer’s personal and professional lives.
Purpose
Who We Are

Ed Deuel
Ed began his law enforcement career at the Whittier Police Department in 1973. He joined the Huntington Beach Police Department in 1977 where his assignments included 14 years with the Special Weapons and Tactics Team (SWAT), Department Training Manager, and over eight years as the Officer-in-Charge of the Crimes against Persons Unit. Since 1980, he has served as a law enforcement trainer for basic and advanced courses in Patrol Procedures and Tactics, Officer-Involved-Shooting Investigations, SWAT Operations, Use of Force, and Trauma Response Team. Ed retired as a Lieutenant after 33 years of distinguished service.
Ed was one of the first to integrate officer safety and post traumatic stress in video law enforcement training. This concept is used nationally by other law enforcement instructors, a testimony to his leadership in this field. Furthermore, Ed has authored various training articles that were published in law enforcement magazines.
Ed has personally debriefed hundreds of peace officers that have survived lethal assaults. Ed was instrumental in the development of a Trauma Response Team at the Huntington Beach Police Department in 1988. He has also helped law enforcement agencies in California and New York create trauma response teams. Ed’s efforts have saved many law enforcement careers.
As the Huntington Beach Police Department’s training manager, Ed worked with the department’s nationally recognized police psychologist, Lawrence N. Blum, PH.D to develop crisis decision-making and use of force scenario training. The skills taught in this program have greatly reduced the shock reactions and sensory distortions in officers confronted with unexpected lethal encounters, and significantly improved their tactical responses in life-threatening incidents. He also initiated ongoing emergency vehicle operation and vehicle pursuit intervention courses that have dramatically reduced officer-involved traffic collisions. The Huntington Beach Police Department awarded Ed the Medal of Merit for his lifetime training contributions.
As a senior member of POST’s Law Enforcement Officers Killed and Assaulted Committee (LEOKA), Ed has studied the assaults and deaths of hundreds of peace officers. He participates in the publication of POST LEOKA and Critical Incident Reports. Ed’s most recent Critical Incident Report is “The Eviction Murders” where a peace officer and a community member were killed in Modesto, California. This report is available for reading or downloading at the LEOKA.ORG web site.
Ed has a Bachelor of Arts Degree in Management from the University of Redlands and a California teaching credential. Since 1980, Ed has served as a law enforcement instructor to thousands of peace officers, receiving commendation for his contributions to the law enforcement profession.

Chuck Moorman
Chuck began his law enforcement experiences in the U. S. Marine Corps in 1957. After his enlistment he joined the Fullerton Police Department in 1960 at age 21 years. He moved to the California Highway Patrol in 1965. In both agencies he had experience as a patrolman, motorcycle officer, field training officer, and acting lieutenant responsibilities at the CHP Zone Headquarters, Los Angeles. By 1969 he had earned a BS Degree in Psychology/Sociology, and an MS Degree in Police Administration at CA State, Los Angeles.
In 1969 he was appointed an Assistant Professor at Georgia State University where he taught Police Science and Sociology, as well as Psychology at Fort Benning Army Base. He also taught six weeks “early-Out’ sessions at Fort Benning for enlisted personnel seeking law enforcement positions after their military discharge. He was certified as a National Rifle Association small arms instructor and taught trainings sessions to civilians.
In 1971 Chuck was invited to join the California National Guard with the rank of Colonel in the newly formed California Specialized Training Institute (CSTI), Camp San Luis Obispo, as one of the original five instructors. Their objective was to teach the mutual aid concept to California law enforcement agencies. In 1972, Chuck noticed the terribly high number of law enforcement officers being murdered in California, 21 in 1970 alone. He commenced researching those murders to extrapolate what occurred that was unsafe, and the safer options available to the victims. With his finding, through the California Peace Officers Standards and Training Commission (POST), CSTI obtained a three-year federal grant in 1973 to develop and implement a 40 hours POST-certified Officer Safety and Field Tactics (OSFT) training program. By the time Chuck retired in 1996, that program had been attended by well over 22,000 law enforcement personnel from every State. It is still offered periodically at CSTI. Chuck developed and implemented other 40 hours POST-certified programs for law enforcement during his CSTI career: OSFT for K-9 Handlers and Supervisors; School Security; Hazardous Materials For First Responders; Commercial Aircraft Crashes Response; and Earthquake Preparedness. In 1975 he earned an MA Degree in Education at Cal-Poly, San Luis Obispo. He holds Life Teaching Credentials in the California Community Colleges (CCC), and the CCC Chief Administrative Officer Credential.
Through his career, Chuck has published two dozen articles on the subject of California Peace officers murdered, and OSFT training. In 1980 he received his Life Membership in the California Peace Officers Association (CPOA). He and Rich Wemmer continue their research and publishing efforts on felonious homicides of California law enforcement officers, to learn from those incidents in order to update and improve OSFT training.

Rich Wemmer
Rich joined the Los Angeles Police Department in 1970, following service at the Pasadena Police Department as a Police Cadet and at the Monterey Park Police Department as a Reserve Police Officer in the late 1960’s. At the Los Angeles Police Department, Rich worked various operational, specialized, and training assignments, promoting to sergeant, lieutenant, and captain. As a lieutenant, he supervised a number of specialized units within the LAPD, including duties as the Officer-in-Charge of the Anti-Terrorist Division’s Investigative Unit during the 1984 Summer Olympic Games, the Hollywood Vice Unit, the Los Angeles International Airport Detail, and the Asian Crime Investigation Unit.
Rich is recognized as a pioneer in law enforcement officer safety and tactics training. In 1974, he started to review critical incidents, especially officer-involved shootings where officers were wounded and killed. He created the “Officer-Involved Shooting” series at LAPD and was responsible for the videotaped re-enactment of over 20 officer-involved shooting incidents. He pioneered the inclusion of interviews with the surviving peace officers, to maximize the impact of lessons learned. Rich also developed the “Officer-Down” course for first responders, supervisors, and command officers.
Rich has authored numerous articles on the murders of peace officers and received awards, commendations, and letters from local, state, and federal law enforcement agencies. His training contributions are recognized nationwide for preventing peace officer deaths; and making the critical difference during a violent encounter.
Rich serves on the committee that studies the assaults, murders, and accidental deaths of California Peace Officers (California Peace Officer Standards and Training, Law Enforcement Officers Killed and Assaulted-POST LEOKA Committee). As a senior LEOKA Committee member, Rich has examined the assaults and deaths of hundreds of peace officers and participated as a subject matter expert in the publication of LEOKA Reports and POST television courses. He created the POST Critical Incident Review Report program to benefit law enforcement personnel. The reports contain tactical and training strategies to effectively prepare peace officers to respond, manage, and survive similar critical incidents. Rich’s most recent Critical Incident Report is “The Eviction Murders” where a peace officer and a community member were killed in Modesto, California. This report is available for reading or downloading at the LEOKA.ORG web site.
Rich received a Bachelor of Science Degree in Police Science and Administration from California State University at Los Angeles, a Master of Science Degree from Pepperdine University in Public Administration and a California Teaching Credential. He is a recognized expert in peace officer training, police tactics, officer safety, use-of-force issues, and the assaults and murders of peace officers.
The California Commission on Peace Officer Standards and Training (POST) awarded Captain Wemmer the “Excellence in Training Lifetime Achievement” award in honor of his contributions and dedication to California Law Enforcement. Thousands of local, state, and federal peace officers have benefited from hearing his officer safety themes of “A Moment in Time,” and “Balancing today’s peace officer as a humanitarian, leader, and tactician” and viewing his training tapes. His comments and officer safety tactics have enabled fellow law enforcement officers nationally and internationally to be effective and safer.

California Reserve Peace Officers Association
The Award of Appreciation for Excellence in Training
In the 1980s, Ed Deuel and Rich Wemmer were deeply concerned with the safety and welfare of law enforcement personnel. Nationwide, more and more peace officers were being assaulted, and far too many were losing their lives on and off-duty. Individually, they recognized that police work was becoming more demanding, difficult, and extremely dangerous. Although initially unknown to each other, their passion for preparing officers to face that “Moment in Time” was a common theme that would eventually unite them.
These two gentlemen have spent two lifetimes teaching peace officers how to stay alive and well during their careers. They have each contributed untold hours providing exceptional training at Annual Reserve Peace Officers Conferences for decades, consistently getting rave reviews and repeat attendees at their courses. It is a distinct pleasure and a high honor to award these gentlemen our first-ever Award of Appreciation for Excellence in Training.
Marcus’ presentation should be heard by every law enforcement officer in the nation! His story is remarkable in and of itself. However, Marcus’ ability to draw on his experience, coupled with his enthusiasm, and ability to relate to and captivate his audience make for an even greater impact. His passion and concern for officer safety can be felt throughout his facilitation of the training. Working with Marcus to bring the LEOKA training to our area was a pleasure. You do not have to interact with him long to know he is an able man of character.
Having known and worked with Capt. Rich Wemmer for 20 years, I believe that his commitment to law enforcement and the safety of our personnel has been one of the paramount goals of his life. The sincerity and professionalism he brings to the LEOKA programs is evident. It should be understood that all this came on the heels of his retirement from the Los Angeles Police Dept. Instead of leaving law enforcement behind, Capt. Wemmer chose instead to share his knowledge and experience in officer safety and sound decision making to the benefit of cops everywhere. Because of his efforts, our profession today is in a much better place.
Rich Wemmer and Marcus Young present compelling, timely training, furnishing thoughtful and critical insights illustrated by historical and recent incidents. Many of our members attend this dynamic team’s class annually knowing that the material will always be fresh, well-presented and a valuable investment of their time.
Golden Badge Award
Top Management Award
Ed Deuel was honored with the “Golden Badge Foundation Honoree, Top Management Award” at the 8th Annual Golden Badge Foundation Awards Presentation in Irvine, California. Ed was recognized for his distinguished law enforcement career of 33 years with the Whittier and Huntington Beach Police Departments. Specifically, he was acknowledged and commended for heroic service in winning a Medal of Valor during a shootout with armed robbery suspects. Although wounded, Ed stopped the suspect who shot him and protected the community members who were present. Furthermore, he was recognized for his leadership and training contributions that have enabled fellow peace officers to be more efficient and safer. His thousands of training hours and trauma response team creativity and contributions have made a significant difference in the welfare and safety of his law enforcement brothers and sisters. Ironically, Ed’s son, Ryan Deuel, recently received a Medal of Valor from the Reedley Police Department. Ryan’s bravery was recognized during the tragic murders of Fresno County Sheriff’s Deputy Joel Wahlenmaier and Reedley Police Officer Javier Bejar.
I have been through thousands of hours of police training seminars and courses throughout my career but none of my training experiences has been quite as compelling as listening to Marcus Young tell his personal story of survival. What made his story so compelling to me was the manner in which it was told. One seldom has the privilege of seeing an instructor who can relay a detailed account of such an emotionally charged, life-changing event in such an open, honest and objective fashion. Anyone attending this presentation will gain a unique perspective on a serious police use-of-force incident and its’ aftermath. Working with Sergeant Young behind the scenes before and after his presentation was also a pleasure. Marcus is one of the most detail oriented and professional instructors that I have met and I would highly recommend him as a speaker at any public safety event…
Sergeant Young has taken a tragic event and magically transformed it into something powerful and positive that is helping officers and trainers everywhere he goes.

Rich, hooah! To a brother warrior, leader, and trainer!
Marcus is one of the leading “use of force” experts in the country. His lecture is an absolutely brilliant presentation on some very important material! I have attended many “use of force” presentations around the country and I would rank his class in the top five mandatory classes that all personnel should take. Marcus is a wealth of knowledge and his own personal experiences makes the lecture riveting.
In 1999, Huntington Beach Police Department Sergeant Ed Deuel received a late night request to assist a peace officer. Whittier Police Officer Mike Martinez had just survived a horrific gun battle and the Department requested Ed respond and provide trauma support.
Ed immediately went to the Whittier Police Department to debrief Officer Martinez. While talking with Mike, Ed noticed Mike’s Whittier Police Department Badge, Number 35. Ironically, this was also Ed’s badge number when he started his law enforcement career in 1973 at the Whittier Police Department. Throughout their discussion, Ed was extremely impressed with Mike’s bravery and he was proud that such a warrior was now wearing his old badge.
Sixteen years later, Ed and Rich Wemmer were asked to speak on “Surviving Critical Incidents” to the Riverside Emergency Services Team Member’s Association in Indio, California. At the conclusion of this presentation, Riverside Sheriff’s Captain Ray Woods commended their contributions and asked Ed to come to the podium.
Moments later, and to Ed’s surprise, Mike Martinez joined them. Mike described their initial meeting and explained that he had since been involved in an additional seven deadly force shootings. He graciously thanked Ed for his efforts in 1999. Mike acknowledged that without Ed’s compassionate care and his unique abilities to make others understand what happens to a peace officer and their loved ones in the aftermath of a violent attack, he would not have been able to successfully deal with the scrutiny of his multiple shooting incidents.
Following this moving expression of appreciation for Ed’s personal efforts, Mike proudly presented retired Lieutenant Ed Deuel with Whittier Police Department Badge Number 35. This memento represents their special memory of Ed helping Mike with “one moment in time” at the Whittier Police Department.
Marcus is one of the most requested and knowledgeable law enforcement trainers in the country. He wrote one of the original Below 100 (www.Below100.com) articles and has done as much to advance officer safety as any individual in the country. Highly Recommended!
Each time I hear Marcus and Rich speak from their hearts on officer safety, they inspire others to learn. I am amazed at their tactical knowledge and passion for officers returning home safely. Their officer safety messages do not hold back and have reached officers across the United States. They have always inspired me to remember the focus on survival is not about me, but the people that need us to come home. I am blessed to call them friends.
