Guess which this is?
I cringed too many times to count watching this video, with yayhoos firing weapons past each other and over their heads while spinning. Yikes! There's a guy in comments defending this shooting school, but I wouldn't go there.
The concept of "Big Boy Rules" and firing weapons over or near someone else is absurd in my opinion, and is an accident waiting to happen. The Marine Corps does live fire with people forward of the firing line, as they would in combat, but those who are forward are not in front of those who are shooting, and even with that it doesn't look anything like this clown show. For starters, there's no choreographed spinning or twisting of the shooters, flagging one another as they transition from one target to the next. And for sure, in real world shootings there are those who have to shoot real close to their fellow Marine or Soldier or Officer, but surprisingly the Marines haven't felt the need to practice that one in peacetime, and it doesn't seem to have effected their lethality. With that in mind I have to question doing it in practice. As far as I know, only a select group or two within the Special Operations community routinely practices live fire with their own down range, and that's because their job description involves shooting bad guys who are in close proximity or direct contact with hostages. I just don't see surgical shooting being a skill set that black-clad mall security needs.
Now I'm going to be all paranoid when I see armed mall security, wondering in the back of my mind if they've been to one of these monkey business shooting schools.
