Defending Against Multiple Assailants Part 2
July 25, 2016
The axiom that street violence is volatile and unpredictable could not hold truer than when facing multiple assailants.  Facing multiple assailants, let alone multiple armed assailants, is an extremely dangerous proposition.  Try to recognize the situation as soon as possible such as if two people are walking towards you and they suddenly fan out to your left and right.  Running and escaping is your best solution.

July 18, 2016
Street violence is volatile and unpredictable.  An attacker will seek every advantage including ambushing you in concert with multiple confederates.  You may well find yourself in a "negative five" position or initially unprepared for the fight of your life.  Krav maga (Hebrew for "contact combat") developed for the Israel Defense Forces will provide you with the instinctive tools and ability to fight for your life and win.
Optimizing Force Using Krav Maga
April 12, 2016
A combative strike will have optimum force if you accelerate your strike in combination with correct body mechanics. Principally, this involves a total body weight shift through the target.

Your strike will generate more force if you accelerate your speed as you extend your arm and put all of your body weight (mass) behind your strike. This requires proper body positioning and technique.

Guns, Knives, and the Hollywood Death Sentence - September 21, 2015
In order to become a successful screenwriter in Hollywood, you need to watch a lot of movies, so you can learn from the screenwriters who came before you, and so you can get a feel for what else is out there and popular today.  Unfortunately, this important part of a screenwriter's education is also how Hollywood ends up propagating and recycling incredibly stupid ideas over and over again to the point where the audience just accepts it without question.
