What would you say is the most useless technique taught in self-defense classes? One that you know would never work in reality? For me, I would have to say telling rape victims to scream "fire" instead of "help." It just doesn't make sense to me. If someone screamed "fire," I would not run TOWARD it...I would run FURTHER AWAY from the sound of the voice yelling it, so as to not die a fiery death! That's just my opinion though. So, how about it?
