Ive belonged to a number of ranges over the years, and yes, a few had range Nazis, some even "GESTAPO".
A good range officer doesnt need to be one, but unfortunately, there seem to be to many, who have no other power in their lives, except when in that capacity at the range, and they like to let you know it. More often than not, it makes for a less than pleasing experience at the range.
While I can shoot in my yard, anytime I want, I do belong to a nice range a couple of minutes down the road, and there are no RO's at all, and we can shoot anything we want, pretty much any way we want, as long as its safe. I have yet to see anyone doing anything that I would consider unsafe, but a lot that you would not have been allowed to do, at most of the other ranges Ive belonged to.
Just because you shoot in a manner that isnt "approved" by some, doesnt mean youre unsafe, or a concern to others.
Perhaps if some of those places that restrict anything but "2 second bullseye" allowed people to practice a little more realistically, they might actually get a chance to learn.
What amazes me is, there are a LOT of people out there carrying guns, who base thier skills on the above, and have never drawn and shot a loaded gun from concealment, while moving. Somehow, that bothers me more than the AK thing.
