Krav Maga ‘for Dummies’? I would hope not. It is an intense martial art, far more intense than any Japanese, French or Brazilian martial art. It works your body to the max and an experienced practitioner can seriously injure an attacker.
This is a comic strip and these are imaginary characters. No one is going to get hurt. Greg Evans is simply telling a story and drawing interest by relating it to real world circumstances.
Remember this is a comic strip, meant to be enjoyed and NOT taken seriously.
