Young is culpable as he has seen the how and why of Wagners moves from one job to another.
Young knew that Wagner was moving to these jobs to develop a background to write and sell around.
Young has known for several years ,just from what has been posted on this forum about the questions about Wagner's BS Bio,and still he pushed the product known as Wagner.
As long as the con was working money was coming in and that is the bottom line.
With Mann,I believe he came to know Wagner through Black Belt and he contacted him.
Mann has a diverse background of Traditional Training and Reality Training and he is/was always looking for more to improve his knowledge and possibly add to his teachings.
Mann has his Asian arts,he has studied with Kelly McCann at the Crucible,he studied with Thorton,Dimitri,WWII combatives and many other arts and systems.
He was fooled by Wagner,as there was NO Info on Wagner or the ability to find what has been found in the last few years.
Mann liked Wagners Basic Approach and became an Instructor under Wagner the same time I did,at the first Reality Based Instructor course in NY.
Wagner put Mann in touch with Aizik and Nardia.
(Mann brought Wagner and Aizik to NY to do their seminars and Cerification programs as Mann had his connection at the Fight House)
Again No way to check these guys out in those days.
Those days wer not that long ago ,but it is long as far as what can be done now in searching as compared to a few short years ago.
(hind sight is a wonderful thing)
We,(Mann,myself and many others like Chris Caile of Fightingarts.com,people with years and decades in the arts and other various training), were all drawn to these guys due to the Bio's they had and put up.
The material were usable and doable,nothing to set bells and whistles off.
Shortly after Wagner and Aizik did their things Mann found Floro Knife and he dropped the Wagner and Aizik materials and he taught/teaches his materials with geat emphasis on Floro Knife/counter Knife.
Mann has been teaching ,traveling,learning and teaching but more and more around Floro materials.
I agree Hock,I am sure Mann was taken in/Conned by Young,through Black Belt and by Wagner and Aizik BS Persona's .
My opinion
