Expertise:  My specialty is crime prevention, crime avoidance and surviving high-risk situations. My books are known internationally as a realistic approach to self-defense and survival in street conditions. I teach police, military and others `professional use of force.` I do have extensive martial arts training, I can answer questions about wing chun, kali and silat and general commercialized martial arts effectiveness in self-defense situations. I cannot answer specific questions about popular sport style martial arts.
In my youth, I was part of the reason the streets of LA were so dangerous. As I matured, I "changed sides" and started being the one telling criminals "no, you can't do that." I bring extensive live-fire experience to the subject.
