Unless you can see a threat you can't defend against a threat. This is my experiences speaking.
This is very true and a well known fact of violence dynamics familiar to all who take up martial arts.
they don't look for the bad things that can happen, they don't read situations correctly.
True, and this exactly what needs to be trained for and it can.
People who have been there many times such as a Rory Miller can teach these aspects of violence dynamics exceedingly well. Even if one is not able to train directly under Rory or others like him…a read of one of his books 'Facing violence' teaches the basics of critical concepts of such confrontations, that if practiced along with the physical, go a long way to avoid falling blind into the trap.
I suggest all readers to become familiar with the following life saving concepts:
1.The monkey dance
2. The group monkey dance that points out to violence occurring when an outsider is caught within the threat group's territory…that serves to strengthen the bond within the group, causing fear and impressions of merciless powers.
3. The educational beat down…where sub-societies [gangs] use violence as an easy way to solve problems as opposed to talking. Being rude and disrespectful in some societies will get you severely beaten or killed. Generally if you are stupid or strutting with a sense of empowerment when you should be demurely polite, when caught in the jaws of a shark, the educational beat down can be merciless.
What Rory teaches here as 'concepts' of violence dynamics is what can be 'trained' to affect the mind set of the individual who may think he has all he needs with some martial arts skills and or some weapons on his person.
as to training for it. Usual scenario training is having somebody in a blue suit shouting at you. then you decide when you have to attack
Generally this is useful to condition a person to handle/manage the adrenaline dump as well as automatically assess the situational circumstances of infinite varieties.
This is precisely the way it was taught by john Farnam and Mas Ayoob in a 'Duelatron' scenario with deadly weapons…the objective being to teach someone to think subconsciously of the unintended consequences of doing vs. not doing. Very effective teaching method when death by weapons is imminent.
I am pretty sure this is what Marcus was referring to. If not…these are and always have been my views on the subject matter.
