Ok there's a lot missing from this because not all of it was wrist lock self defense. Maybe they forgot to do the chokes and bear hug self defense for some reason. I don't think this guy was doing any of these in the right order and didn't involve the ones taught in Traditional TKD.
But number 8 was the one I remember from TKD. I swear I remember one in a headlock position where you push with one hand in the attacker's eyes and one leg behind the assailant's leg, doing a leg sweep. And to finish off part I don't remember, I thought it was either an axe kick or stomp or a punch to the head. That's what I could recall from TKD.
