I know you're so used to it, Don, but I think you jumped the gun when you brought out the F-word (fraud). The first thing I thought of when I saw the words "traditional" and "ninpo" in Bushi's post was =Genbukan.
A quick search on Paul Lawrence brings up mention of the Kurama Dojo which is a Genbukan Dojo.
Likely what happened, is Mr. Lawrence started in the Bujinkan, got his 5th dan - 7th dan from Hatsumi, then switched over to Genbukan.
It is still a bit fishy since on the website, Mr. Lawrence only credits Hatsumi for his rank and only mentions Tanemura in the sense of "...also had the honour of training under Grandmaster Shoto Tanemura."
So he might no longer be a member of the Bujinkan, but might also not yet have teaching credentials for Genbukan.
Bushi, do you know any more details on why he had to close the dojo?
"...he said that Sensei Paul is recognised, only in a different school than Bujinkan..."
He's probably recognized in Genbukan, but recognized as a student, or as an instructor?
Regardless of any of the above, if you have a Bujinkan dojo in the area, go there and train, I'm sure you'll find what you're looking for.
And yes, syllabi and curricula varies from instructor to instructor in the Bujinkan. I assume though that a Tenchijin Dojo would use the Tenchijin Ryaku no Maki as a training guide.
