Power Parent: How to Keep Your Kids Safe Book

So, I checked this book out of the library on a whim, because I occasionally teach karate, and some of the people I teach are women.

The central thesis of this book seems to be that self-defense courses for women should take into account that women are more likely to be attacked by some one they know, rather than a stranger. Thus, a self defense course should incorporate lessons on boundary setting and other social-psychological techniques, etc. And, if part of the purpose of martial arts is self defense, then martial arts courses should incorporate those techniques as well.

The central thesis seems to make sense, but there is not much evidence offered to support it (like, do the techniques the advocate the teaching of actually work?), and I'm not exactly even sure what the techniques they are referring to are, yet a lone how to teach them. Of course, Lawler suggests I can't actually teach them any way, due to being male.

It also comes off as vaguely paranoid often, which I suppose is a common flaw in books about self defense.
