Just finished the video. It's reckless that he's teaching this as actual, real time, self defense. His students may actually believe they have an increased chance of survival using his "swim dance defense" thing *sorry, don't know what else to call it.* Maybe multiple attackers may be repelled by the gayness of the movement? If that's the goal, maybe he's on to something...otherwise poor poor chumps paid money for his class/seminar.
