History In Ed Parker's own Words

Coming originally from American Kenpo, we learned much technique. I have read in Black Belt Magazine dated Augest 1990, Ed Parkers' take on James Mitose. It is written very simular to the above article.

If Mitose's moves were impractical as Ed Parker once claimed, then why does one of his earlier books on self defense shows technique that looks identical to that of Mitose's?
