I do find this very hard to believe - you are saying that Ninjutsu is against the law? Can you provide substantiation for that claim?

I have nothing that I can link to, no. I only have what I've read in the past, or learned via other channels.

Since my last post, I have looked at all of the information contained in the pages that came up from the names you sited; and every single one of them...short of the GrandMaster, and the two pupils of his who can legitimately lay claim to actually learning the style from him; everyone else has stated that the art they teach has been derived from the original, but is not the original. That's all I had said originally.
