Thanks for the comment. You pose a very reasonable point here. The information IS out there. This was a very hard personal choice for me, and undoubtedly will have financial impacts. The guys that do these videos can easily generate interest to fill classes. When I first started my training business, I had plans for all kinds of videos- including vignettes in CQB and Vehicle Tactics. My turning point was the days following 08 July 2016. Late that night I started receiving calls from close friends who were in downtown Dallas at some of the bars and clubs. They were sheltering in place. I then started receiving texts form Dallas police officers and SWAT officers about what was happening.These were good friends of mine and my concern for them was very real. In the following days, details began coming out about the Active Shooter. He trained with a Texas based outfit. He was reported to have been observed practicing barricade drills in his backyard. And- his web browsing history revealed that he watched many of the more popular instructor's RU-vid training videos. At that moment the though popped in my mind- what if it had been my videos he watched, what if the tactics and techniques that I saw on the video footage of him killing those that serve our community were learned from me? That is a pretty tough thought. Of course it is impossible to 100% be sure that someone attending a course won't go crazy and do something stupid. But at least by limiting certain information dissimilation to courses, I feel that I am taking reasonable measures that are prudent. I also gives me the opportunity to meet the student, look them in the eye, and make an assessment about them. Depending on how I asses the sensitivity of the course, the vetting required is also increased. Anyways- that's my point of view and the thought process that led to it. If you don't agree with it- then as you said, the information is out there for you to view from others. Thanks for your comment.
My thought is less about national security (tactics aren't secret, strategies are, and strategies are diverse, plus our enemies have vets of their own who teach them from experience to fill the gaps) but more about intellectual properties. Your training is your business so it makes little sense for you to give it away in a free video. Either way, I support you doing you. I'm glad you are pro 2A (helping with CCW permit) and that you vet out your students. All trainers should do the same. Personally I also do a political survey, but that is because I don't teach for a living.
