Well, they've clearly mastered the secret art of Teh Sexxay with that 5th dan black belt doing katana work in a shimmery camisole.

The website looks pretty loopy but who can say based on that. The following doesn't look promising; "American Kenpo Bu-Jutsu is a system of self-defense in which people
learn how to end a confrontation...it is a no-holds barred system of self-defense. American Kenpo
Bu-Jutsu doesn't train with non-lethal techniques, nor does it train to back up after a technique is
executed. Students train to attack with the most lethal techniques in their arsenal and to keep
attacking until the threat is destroyed." That sort of language and phraseology sets off alarm bells.
At the end of the day though, nothing you can find on the web will answer the matter for sure. Have your friend go observe a class. Even if your friend doesn't have alot of MA experience, that is still the best way to go. Look for the presence of sparring (preferably continuous w/ some good contact), resistive training in the drills, and hard working students. Look out for schools that refuse to spar, especially if they claim it is because their art is "too deadly." Also look out for claims that their art is the most perfect in the universe, or anything about invincibility, no touch knockouts, and one hit kills. On the McDojo side, look out for long, locked in contracts, or if they refuse to let you watch a class and sparring session without signing up.
