The guy's arrogant and ignorant. Who does he think taught "them" (all the SF branches) all those high-speed things regarding small arms ....... uh, civilians.
Back when the action shooting sports started really gaining traction, some "operatives" started showing up at these events and were routinely getting their butts handed to them by CPA's, plumbers and forklift operators. They went back behind the wired fences and rather quietly solicited the services of guys like John Shaw and several others to teach them how to shoot.
