It is wildly irresponsible of Dr. Piazza to even make video of such stupidity available on his site. Similar links have been posted here before, and I don't like it now any better than I did then. This is not "training" in any guise any normal armed citizen could consider as such, and no one should consider this sort of demonstration any more than recklessly dangerous showboating.
Please refrain from posting dangerous stunts like this one here in ST&T. This IS NOT training in any sense of the word, this is stupidity. There is a gracious plenty of gratuitous stupidity available in the world already, without encouraging people to conduct more of it. This IS NOT what goes on in any professional training venue. And it is highly unprofessional and wildly irresponsible of Piazza to have kept this video available on his site for years now, even as a demonstration of what they don't do at Front Sight. Even hosting it gives it a sort of backhanded credence, as well as wider exposure, which is why I don't like having such nonsense posted here.
