In Tae Kwon Do, we're always told that no matter what you do, you take whatever chance you can to RUN. Like, LEG IT! Also, make sure you have a will to survive, no matter what happens. If something goes wrong, and you're in danger, fight for your life! Even if half your arm's chopped off, use the other half to smash the hell out of them. If you're trapped in an abandoned warehouse with some rapists, think of it as them being trapped with you! There are heaps of ways you can fend off criminals, just don't freak out and maintain your confidence.
