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.
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.
Interpreting The Kanji - June 2, 2015
Studying an Asian martial art can be a daunting task for a non-Asian student. Not only do you have to learn the physical postures and how to move from one to the other, you also strive to master the seemingly endless number of techniques. As well, the cultural milieu in which the martial art developed is often confusing. Many times the task you undertake is compared to climbing a mountain, and for good reason.
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.
Gichin Funakoshi (1868–1957):  The Gentle Teacher of Shuri Te - December 1, 2014
Perhaps it was always Funakoshi's destiny to shed light on a part of Okinawan culture that had for centuries remained hidden from the gaze of the general population. He shone like a bright star in a dark sky and pointed the way forward for the many millions around the world who would take up the challenge of learning.
Fond Memories About Okinawan Cuisine - November 3, 2014
I once asked a Japanese friend of mine, who had flown down from the mainland to Okinawa to meet me, if she was enjoying her visit to this part of Japan. Her reply surprised me at the time, as she confessed it was like visiting a different country. The food in particular was very different from the type of dishes she ate on a daily basis with her family in Osaka.
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.
Modern Trends: Reality-based Martial Arts - September 15, 2014
The rise in recent years of so-called ‘reality’ based martial arts reminds me of other great scams committed against the general public, like bottled water, and who can forget the panic that gripped the world in the 1990s over the Y2K dilemma that was supposedly going to see aeroplanes fall from the sky and shut down every computer on the entire planet.
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.
Bunbu Ryo Do: The Way of The Karate Martial Scholar - March 10, 2014
In the early part of the twentieth century, when Okinawan karate teachers were first asked to provide names for their karate by the Butokukai in Japan, they struggled to come up with a name that did justice to the martial art they practiced.
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.
Difficult Research in Developing Karate—Part 2 - November 11, 2013
Personal research requires you to look inward towards your own nature, and to take responsibility for your karate; to step out of your comfort zone. You can do this by attending events like open courses if you like, but in truth, such challenges do little to aid your progress.
Difficult Research in Developing Karate—Part 1 - November 4, 2013
“Karate training is easy!” Now there’s a statement to get your head around. But is there any truth to it; is training in karate easy? Well, children, the unfit, the lazy, and folks of dubious character…all seem to have no problem being awarded a black belt in karate these days, so the training must be easy…right?
Unraveling Knots in The Thread of Life - October 14, 2013
Over a period of about eight years, beginning in the early 1990s, I began taking a closer look around the world at the various religious and philosophical beliefs people held, and saw in many of them much to be admired. I also noticed there was quite a lot of common ground. I was initially astonished to discover, for example, how the sacred text of Judaism, the Torah, tells the same story as the first five books of the Bible, known to Christians as the books of the Old Testament.
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.
From Whence We Came: Some Okinawa Cultural Icons - April 8, 2013
At a little over 26 degrees north of the equator, Okinawa enjoys a subtropical climate, and for much of the year its inhabitants live under clear blue skies. However, during the early summer months, typhoons sweep in off the Pacific Ocean bringing with them strong winds and huge seas often resulting in damage to property, and sometimes loss of life.
Karate-A Unique Balanced Approach to Healthy Living - February 26, 2013
Those who enter a dojo for the purpose of maintaining good health engage in a training routine that may look similar to those engaged in budo karate, but this similarity exists only on the surface.
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.
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.
