Salt Lake City, Utah, asshole grabs Michelle Adams, gets kicked and she reverses his grab, "Adams credits her martial arts training. She says, “I remember this move that my karate teacher showed me in third grade. You twist your hand around, it hurts their hand and they let go.""

As an instructor says in the article, "...his goal is to arm them with tools to buy them time, seconds that could mean life or death. The idea is to teach them one technique. You get one chance. Stun your opponent and then the child screams, yells, and they’re told to find the nearest adult.”

This gets me back to the warnings I've heard to never think of self-defense as a fight. She would have lost a fight, but she escaped using martial arts.
