It is interesting that some of the posts are from a view of already in the fight and in the process of destroying the attacker(s). Whether you have to destroy someboy is totally based on the individual situation.
I would say the goal of Kenpo would be control and awareness of the situation from it's inception to it's completion. And as TOD has posted if you have that much control of the situation you should be able to negate it very early and without violence...that would be Kenpo to me. How much more efficient could you get?
Of course if it comes to blows then we continue to dominate and control by having our opponents continually react to our attacks in a way that gives us the advantage and puts them at a disadvantage. If that involves throws, locks, strikes, kicks, then so be it....we'll use it all as we see fit.
One more thing, from an outsiders point of view, all they see is the SD techniques and I'll admit they are brutal, but they are just a part of a overall response to any threat.
