Why does everyone preach Martial Arts????
It's great of you're young or in good shape, or a cop, But???
Thank about it, bandits choose what appears to be the weakest target. They aren't total idiots.
If giving a choice they are going to choose the elderly, the young mother, etc. not the young spry looking individual.
I guess you should tailor your class to your students, and you have young, in shape individuals, the throw in the MA's.
Most of my students don't fit that category, most are young mothers, middle age to elderly.
If the victim is a young mother towing a toddler, she isn't going to loose the child and drop into some sort of MA stance. She's going to pull the child behind her for cover and use a revolver/pistol to ward off the attacker, more then likely with one hand (she is still holding the child behind her body).
I digress.
My other concern with the video is the distance involved. Seems like the farther you are from the bandit, the harder to justify self defense.
Think about it, if you are trying to prove you were in danger, wouldn't it be easier if you left powder burns on the bandit?
The video seems to deal more with active shooters then the more common one on one strong arm or car jacking.
Active shooting has been covered quite a bit on these forums, basically, leave if you can, hunker down if you can't, be prepared to shoot if there is no other choice OR to leave your gun in your pocket with empty hands displayed if the cops show up. When you're hunkered down, you don't know who is going to be popping around the corner.
I like to tell people to read every incident of robbery, car jacking, purse snatching, etc. they can to see what is happening in the real world and adjust your training accordingly.
Make friends with local cops so they can tell you the type crimes found in your area and adjust your training accordingly.
Just some thoughts.
