Our Team


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.


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.

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.

Officer Ron J. Kooper

United States Coast Guard, LA

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.

R. K. Miller

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…

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.

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.
