You do not understand the subject matter.
These were not demonstrations of what a real fight is supposed to look like. These were drills that are meant to train the practicioner to do well in combat. Since you can't practice everything in these arts as is without killing someone with a sword, you have to take one part then another and then another and put them all together.
You might notice that one of the first demos had a guy from Araki ryu wrap a chain around another's neck and then the guy with the chain around his neck just stood there until the guy threw him. That is not realistic by any means. But unless you want to take the chance of snapping someone's kneck during practice, you can't just do it as a free for all event. There are ways of training to deal with resistence, but that is not being done at the time in this demo.
I would like to point out to you that these demonstrations were done at a gathering in Japan of people who do these types of things so that they can learn and exchange ideas as well as build a sense of community. Your later comment of,
shows how you look at things based on your experiences in America with no link or knowledge of what is going on in Japan. These demos were not made for the likes of you. The intended audience would be experienced martial artists that did similar stuff. They want to know more about the lessons of the past and see what the ancient forms were. Your comments about demos seem to indicate that you think of them as mainly ways of attracting students. But these were not done at a shopping mall, but at a gathering of like- minded individuals.
As others have said, there is a lot more going on than meets the eye and the people these demos were intended for were not folks that had no experience in training in koryu and were merely surfing the net. As such, they did not go through the explinations and introductions of the underlying stuff so that even you could understand it. I know of schools that do not want their stuff on the internet at all because of this type of problem with matching levels of experience with the medium. But please remember that these guys who were demonstrating were doing so with the expectation of showing what they do to people with far greater ability to catch the subtleties through their experience. Somebody else put it on the internet so that the rest of us could see it- even if we do not understand everything going on behind the curtains.
I do indeed understand the subject matter. And I do know that demos with live blades and weapons must be done with care and control. I do look at things based on my experience and observations. And my experience and observations tells me that some of this stuff just won't work.
