Because you need to have *PERMISSION* to post it publicly for the world to consume. I guarantee you that this individual *NEVER* received permission from Noguchi-sensei to plaster this lesson all over the world.
Well ; in this case the stuff shown could indeed be picked up from just one teacher.
But even so ; is it exactly 100% indentical?
Personally ; i don't think so.
It's an interpetation of something that somebody saw imho.
What is the problem of showing just a bit of video about some of the various interpetations that came along during a training?
The way i see it , it's a nice insight of something that was shown before.
Something that you can enjoy and maybe even learn from, thats what it does for me at least
The problem is that when people do not ask, and it gets back to the Shihan that people who are given permission to film "for their dojo" are actually plastering it on the internet, well, the well will dry up quickly.
Allow me being the devils advocate here ; since i've spotted dozens of people camming during various sessions at hombu this year ( not just one or two people but about 10 lenses or so... ) it seems to me that it's actually getting more "eased up "
Don't get me wrong ; i found it to be quite disturbing.
I admit ; during my first trip i also tried to get some of the classes on video ( with permission from the shihan teaching of course ) but then just a few people were camming , in just a few years it seems that more and more people are joining in...
Given the way that certain people actively criticize Bujinkan training as "dead" or whatever ...
They'll keep on flaming ; if they don't have the video they'll get some other rotten eggs to throw with.
You can have your day absolutely #censored!# by that or you can let the criticasters just shout like they're air.
