There's an old, sort of humorous saying about the education business (my wife is a retired professor, I'm a retired librarian with several years spent in the university environment):
"Those who can, do. Those who can't, teach."
And when I was working in the College of Education Library at the University of Alabama (Tuscaloosa) in the mid-1970's, I heard another variation:
"Those who can, do. Those who can't, teach. Those who can't teach, teach teachers."
fwiw...
I spent the longest part of my working life at USAJFKSWCS at Ft. Bragg, NC. That's the schoolhouse where Special Forces soldiers are trained. The first class everyone took when they were assigned to JFK when I was there was the ITC- Instructor Training Course. They taught you how to teach the Army way (tell 'em what you're gonna tell 'em, tell 'em, and then tell 'em what you told 'em, is the old joke about that one). A lot of people don't really get it that SF soldiers are basically schoolteachers who get to work via parachute, but their primary role is as trainers and teachers.
And they are good, as a rule. Many of them are VERY good. Then you get to see that special class of people like the dozens of folks I knew who were in uniform for a full SF career, retired, and then spent another 20 years or more teaching new SFers the tricks of the trade. Many of them were and are exceptional trainers and teachers.
I've paid for training with a number of professional defensive firearms trainers. I think I'm in as good a position as anyone I know to evaluate that training. And so far, every pro I have trained with has been more than worth my time and money. How many of them have shot and been shot at? I know Louis Awerbuck has, there was no doubt about Jim Cirillo. I don't know about some of the others, some were or are wearing badges, have spent time in the military, etc. but I don't know personal histories. No one notches their guns after all, at least no one I would consider worth training with.
What it boils down to as far as I am concerned is #1, what do they know, and #2, how well can they impart that knowledge to their students?
The absolute best do what they do because they can't NOT do it. Training is not what they do, it's what they ARE. It takes seeing someone like Louis Awerbuck at work to really appreciate what you're watching- if you know what you're looking at, that is. I genuinely love to see an exceptional trainer at work. It's a remarkable experience, and one I wish everyone here could- and would- share.
