After Parker's death, American Kenpo turned to no more than a MCDOJO. Every student seem to establish their own school and teach a bit of karate, a bit of taekwondo, a bit of BJJ.
One good example is Jeff Speakman's Kenpo 5.0. How can you put a number after a karate name, if it originated from Okinawa? Is there a Kyokushin version 1, version 2, etc?
Kenpo 5.0 is a joke, it even copied BJJ moves to its arsenal and call it its own...
