The Lowest Level of Force
December 7, 2020
The Records area at Rusafa Prison Complex in Baghdad is enclosed by a chain-link fence and was almost always crowded. It’s a stressful place, with inmates being processed in and out, Iraqi military, police, corrections, advocates, politicos, and sometimes families of the convicts are present and a small handful of American advisors.
Brain Damage: Do Football Helmets Help?
September 5, 2016
Recently, the National Football League is facing a 765-million-dollar lawsuit filed on behalf of more than 4,500 former players regarding the concussions and potential chronic traumatic encephalopathy (CTE) sustained during their careers. Similar lawsuits are underway against the National Collegiate Athletic Association as well as the National Hockey League, and football helmet maker Riddell is facing multiple lawsuits over claims about the effectiveness of their helmets at protecting athletes from concussions.
The Donkey
March 7, 2016
I am not, nor have I ever been, the most physically competent martial artist. It takes me inordinately more classes to attain technical proficiency in many areas than it does others. I am tall and fairly agile, but I do not have much muscle mass. And then, over the past few years, two significant medical challenges have crossed my desk. Couple all this with the fact that I am now in my 60s, and a potentially bleak image begins to materialize.
Foam or Knuckles—Navigating the Illusion of Safety
January 18, 2016
If you really want to understand how gloves contribute to the safety of our athletes, especially when it comes to their brains, take a closer look at the physics behind taking a punch with a bare fist or a glove.
Guns, Knives, and the Hollywood Death Sentence
September 21, 2015
In order to become a successful screenwriter in Hollywood, you need to watch a lot of movies, so you can learn from the screenwriters who came before you, and so you can get a feel for what else is out there and popular today.  Unfortunately, this important part of a screenwriter's education is also how Hollywood ends up propagating and recycling incredibly stupid ideas over and over again to the point where the audience just accepts it without question.
Protecting the Brain from Trauma: A Home Experiment to Show We Can Do Better - September 7, 2015
If you put on a football helmet right now and smacked yourself in the head with your hands, you might notice you can hit yourself pretty hard before you start to feel pain. You could even grab a stapler or a coffee mug and hit yourself with that. If you are like me, smacking yourself in the head is the first thing you do when you put a helmet on, just to test it out.
The Players in Self-Defense - February 2, 2015
No matter what levels of force you need, the players stay the same. It is critical to be able to read the players. The threat dictates the situation. You must understand the problem before you can choose a solution. A charm predator is one thing. A drunk wanting to show off for a girl is an entirely different problem. You must learn to read threats and threat dynamics.
Avoiding Workplace Violence - January 26, 2015
According to the National Institute for Occupational Safety and Health, 18,000 people a week are victimized by some sort of workplace violence in the United States. In fact, although industrial accidents abound, homicide is actually the leading cause of death among female workers and the second leading cause of death for men.
I.M.O.P. Principle—Intent, Means, Opportunity and Preclusion - October 6, 2014
How do you know when it is legal to get physical with an adversary? Learn the I.M.O.P. (Intent, Means, Opportunity, and Preclusion) principle. All four of these criteria must be met before you have a good case for taking action. If one or more of these conditions are absent, you are on shaky legal ground.
Account for Adrenaline - September 1, 2014
When I took a defensive handgun course several years ago, I was taught to train for handling the survival-stress reaction commonly associated with actual combat. To simulate the reaction, we had to do as many pushups as we could as fast as we could for one minute.
Political Turmoil in Taekwondo - August 18, 2014
On December 31, 2013, Grandmaster Kyu Hyung Lee, taekwondoist extraordinaire, formally resigned his post as president of the esteemed Kukkiwon after holding the position for a mere matter of months. Quickly replaced by Man Soon Jang, Lee claimed his startling decision was founded on irreconcilable differences between two leading factions; one consisting of officials whose behavior is largely motivated by politics, and a second group of martial artists, spearheaded by Lee, with the purity of taekwondo at heart.
The Heart of Taekwondo - July 7, 2014
When the heart of taekwondo beats, it gives life to the advancement of supreme discipline, the achievement of noble character, and the cultivation of an enlightened worldview. It breaks the bonds that bind us to the Earth and again, as adults, allows us to feel the wind beneath our feet rather than merely around them.
The Victim Interview - February 17, 2014
I was parked alongside a major street in downtown Seattle. My hands were full of boxes and the mid-afternoon sun was glaring in my face, making it hard to see despite my polarized glasses, so it took a couple tries to get my key into the lock. I awkwardly dragged the door open, nearly dropping some of my packages, and began shoving my purchases in to the car.
History and Philosophy of Taekwondo - Part 2 - August 5, 2013
Similarly rooted in Chinese culture, the Baduanjin routine, or Eight Pieces of Brocade, a medical qigong therapy whose performance is professed to impart a silken quality to the body, dates back to AD 1300 where it appears in the Xiuzhen shi-shu (Ten Compilations on Cultivating Perfection).
History and Philosophy of Taekwondo - Part 1 - July 29, 2013
Long before the advent of sport sparring and the invention of modern safety gear, in a time when to fight meant to defend one’s life from almost certain death, an ingenious method of transmitting martial arts skills from venerated master to loyal disciple was developed.
Understanding Learning Style Differences - June 24, 2013
I realized fairly early in life that different people learn and process information in different ways. When teaching and learning styles misalign, students progress slowly, if at all. As a child, I had the opportunity to take judo instruction from a former national champion who was the highest-ranking black belt in the United States at that time.
The Evolution of Tae Kwon Do Poomsae, Hyung and Tul-Part 2 - June 17, 2013
Throughout the 1950s and early 60s, when Tae Kwon Do, still referred to as taesoodo, tangsoodo and kongsoodo in many circles, was in its infancy, poomsae practice consisted largely of exercises derived from these Okinawan, Japanese and Chinese disciplines.
The Evolution of Tae Kwon Do Poomsae, Hyung and Tul-Part 1 - June 10, 2013

Karate - A Fighting Art: Use Technology - February 18, 2013
I began training in the martial arts in the summer of 1965. Months earlier, I had broken my lower back in a weightlifting contest and the doctor told me to stop lifting weights and to try something less violent on the body. Therefore, I began karate training.
Lethal Force: Firearms - Part 2 - February 1, 2013
Don’t over-romanticize guns. A handgun  is a nifty machine that throws a hunk of metal in a straight line. No more, no less. A .45 caliber bullet, unless it hits bone and sends fragments spinning, does just as much damage as driving a blunt 45/100 of an inch-diameter stick into the body.
Lethal Force: Firearms - Part 1 - January 28, 2013
While handguns, shotguns, rifles, and carbines can all be used in self-defense, it can be very challenging to justify anything other than a handgun in court, save for in your home (or some places of business) where castle laws might apply.
Surrender! Clear Your Mind To Learn A New Skill - January 14, 2013
After teaching taekwondo for many years, I have come to some concrete observations. As an instructor and school owner I have noticed that many new students have a difficult time acclimating to Eastern customs.
Level 6-Lethal Force - November 19, 2012
Gary Fadden was a salesman for firearms manufacturer Heckler & Koch. On February 24, 1984, he and his fiancé were driving their Ford pickup along Route 50 in Virginia. This was before cell phones became ubiquitous and he had no communication device inside his vehicle.
Understand Strength versus Skill - November 12, 2012
Understanding your place in life is always a good thing. However, in the world of martial arts some times it can be hard to know. In the real world, the employer and employee are clearly defined; parent, child is another example. However, the martial arts are based on skills.
Interlude-On Killing - October 22, 2012
I don’t shoot targets. I shoot men. Honestly, I figure I owe them that much. I know that when I kill someone I am doing to their family-their mothers and sisters and brothers—what the assh*le who murdered my sister did to mine. My mother will never recover all her sanity from that. She won’t ever stop grieving.
