Wow class act and professional! Since you have no idea about my "limited" but extensive military and law enforcement training Ill leave that line alone, as far as mindset Im very open minded when presented with fact not opinion that can't be backed up or that goes against lots of proven fact. You say you can disprove most of what is taught in every other class why are you right and everyone else wrong? I will always listen when approached professionally and talked to not at. I am always open to learn more and to better myself. For you to say other wise is again unprofessional as an instructor. What I believe is in what works and what has been proven to work.
I definitely do understand defensive firearms training principals. And it doesn't have to be suicidal that is a crazy statement. Again you haven't answered any questions but just bash and insult. You are in this for money. and that is it trying to make a name for your self. And again I say that everything in that video can be proven wrong.
