Looking at the demo videos and iTunes stuff, it seems that most of the self-defense techniques involve yelling "Stop it!" instead of a kiai. I am guessing that is a legal protection thing. After all, if you mave a few moves and the attacker is on the ground, it could easily look like the defender was the attacker. But why does it have to be on each move? A block, shuto, kick and punch in rapid succession make the defender sound spastic."Stop it! Stop it! Stop it! Stop it!" Is that because the persons a newto self defense and you're trying to get them to learn to exhale on each technique? Please tell me that once you get the idea you can drop it down to one or two for an entire encounter? Like one at the start of a technique and one if you have to re-engage after the first combination.
