De-escalation training comes from the idea that in a workplace or in a public place, the best method to avoid violence it to try and calm down a possible attacker and thus avoid a confrontation all together.
Of course it is an involved attempt to prevent a slow pace violence to escalate into a fast pace violence. Perhaps it is also an attempt to control the force of response to violence only to be used as necessary to protect oneself.
Not being thoroughly familiar with the components of possibilities could only increase the level of being subject to a harmful threat!
Some violence is well thought of, and some tends to escalate in nature. Some attackers, angry customers, citizens, employees take their time and plan their act of violence. Some has a plan in process that increases its intensity during the confrontation usually in proportion to the level increase in anger or dissatisfaction.
In any case for the unfortunate un-expecting victim, who is caught by surprise but might notice the signs of upcoming confrontation or might feel them out of the blue, trying to deescalate the situation might cause the element of surprise to be lost.
While the perpetrator often use the element of surprise, as the human nature and experience dictates, picking up of lesser threatening people not to risk injuring himself, the defender is often using the element of surprise back and cause reversal of fortune.
To makes the long argument short, let’s say someone verbally or physically crosses the social boundaries to get what he/she wants disregarding your own physical and audible boundaries.
The first signs of this happening should be used to your advantage to counter it with greater resistance to surprise the attacker back without giving him a possibility to retreat and calculate a better resistance to your actions, unless you are certain you have the resources to counter them back!
Depending on the environment, your resources, you should know what your capabilities are and have a good judgment of how your confrontation could turn into a life or health threatening situation.
It is of course about judgment and about not being misinformed. You get your bearings set by what you read and hear and watch happening in your environment, and from your personal sense of how safe you are.
Of course, when a possible attacker is getting close to you and crosses into your personal territory he might inflict harm upon you before anyone else might be able to help you.
In terms of Hand To Hand Combat it means that once someone showed a physical intention to hurt you unless you assess him as a very low threat potential, you need to neutralize him.
If you are familiar with the human weapon potential, you should know that a strike, a kick, a stab or a strike with a blunt object, could immediately make you unconscious or take your life as well. A choke or limb manipulation could also cause death or severe injury but takes few more seconds to accomplish.
Of course a skilled attacker could move from one motion to another within a matter of split seconds, so just because he is standing in one position do not assume that if you need to fight him he might not attempt to change his position few times before it is all over.
So as long as you are aware of the Fighting Capabilities of the Human Body, and are able to apply working solutions to them, and you know that if you talk, scream or yell at this person, you are not slowing your capabilities to react to a threat (depending on the gap between you and your opponent in each moment, you can attempt to deescalate a potential fight.
But if you think about the worst thing that can happen think of how you could lose the element of surprise.
Your opponent has lost his when he showed you signs of violence… If you are a small female for example and a strong man is trying to hurt you and instead of kicking him in the groin first and then plucking his windpipe or testicles you threaten him by calling the cops when he already grabbed you , or can extend his arm and grab you, you are losing the element of surprise.
While you talk to him he could finish what he started, or pause, listen to you, and make up his mind and then finish what he started and surprise you again. In fact you should have kicked him before he got closer and was able to reach you.
You could have called the cops, if your door was locked and he could not hear you and he was not in the middle of breaking your door while you are standing behind it with no place to hide…
You do not have to be a small female being attacked by a strong man. You could just be any normal individual who might be out powered due to weight height, level of fitness, and level of badness. A blade, a blunt object of bad intention could change the balance of powers at any moment.
Only of you are confident that you command control of your safety in tight spaces and aware of the human body limits you can control your space and allow various levels of de-escalation in a particular scenario…
The deescalation process does not necessarily means the use of one technique or another. Instead you might want to increase in the quantity of weaker strikes using less power to achieve increase in nerve control and decrease in injury.
Perhaps your only resort to deescalate the violence is to instantly kill your opponent to prevent harm to your body. Once an opponent gained advantage in the element of surprise he can escalate it to higher levels.
The key is response in the constraint of reaction time. If you run out of time and distance between you and your opponent, you will not be able to identify his next move and respond to it properly.
Your mind might still be analyzing and thinking about how to response during the split second he get you unconscious and then choke you to death after or cutting you to pieces after the first stab or cut if not in vital organs. Remember you need time to process what you see and to use your body as a weapon.
If he is using his body as a weapon first there is a point where the combination of seeing what is about to happen and what is about to happen actually happens is happening and if it is happening while you are seeing it and not at the point of you responding to it – it will happen!
Generally when we see someone attacking, we might conclude that he is guilty in creating violence. Hopefully law makers would realize that you have a right to live, and if someone is trying to take it away from you, you might kill him.
More important, they need to realize what the breakeven point of no return is. You cannot really afford to wait until you are distracted with a slap.
That might confuse you and buy your attacker time to kill you. It should be unacceptable from society to expect you to bleed to death before you are allowed to kill as self defense.
At the same token it is illogical to be expected to wait until the opponent's blade in your territory speeding to your heart. Reaction time should be the break-even point to determine if killing someone could have been avoided or not.
