A fundamental flaw in logic that I see a lot in the education field, and in the firearms training field, is that if someone can do something well, they are a good teacher of that skill. I know a guy that works for micrisoft in cryptography, before getting their his math skills got him 11 different college teaching jobs that he lost all of because he sucks as a teacher. I would want toknow a lot more about someone than that they were a seal before taking their classes.
And as far as getting in person training, with videos nobody is going to correct your mistakes and you will probably mislearn some very bad habits. I think videos should stick to teaching tactics, and stay away from technique.
