What is Self-Defense?

When it comes to self-defense, especially with firearms, it is extremely important understand what the laws stipulate. This question has been asked in our classes: “If someone is stealing my car, can I shoot them?” The short answer is NO! Unless they are posing a threat to you or a third person, you cannot use deadly force.

According to the Colorado Revises Statutes on Use of Force 18-1-704. Use of physical force in defense of a person: a person is justified in using physical force upon another person in order to defend himself or a third person from what he reasonably believes to be the use or imminent use of unlawful physical force by that other person, and he may use a degree of force which he reasonably believes to be necessary for that purpose.”

Ok, does that clear it up? Probably not quite. For example, what does it mean when it says “reasonable?” In the Criminal Justice world reasonable means what does the judge and/or jury think is reasonable. In other words: can you justify your actions in a court of law. When a peace officer is involved in a deadly shooting incident the procedure that is followed is to put that officer on a 72 hour administrative leave. This means that officer does not have to write a report or answer questions about the incident for three days. Why is that? It is because medical research has shown us that that officer will not be able to accurately describe the incident as it unfolded. Why? It is necessary to understand this: Under combat stress your body will have involuntary reactions that include: Vasoconstriction: the blood vessels will constrict inhibiting the flow of blood to your extremities, your arms, legs, and head.

1. Loss of depth perception. The shape of the eye will change and it will inhibit your ability to judge distances.

2. Loss of peripheral vision. You will not see things to the sides of you.

3. Auditory exclusion. You will not react to sounds very well if at all.

4. Loss of fine and complex motor skills. You will not be able to write your name, dial a phone or reload a firearm well.

This is why we spend time in the class room and at the range practicing what to say and what to do. We practice “after action drills” so that you can mitigate some of the effects of the adrenalin pumping through your veins.

    According to the U.S. Department of Justice, millions of citizens are victimized annually by personal theft, violent, and property crimes. You do not have to be a statistic. Experts agree the single most important factor in surviving criminal attack is to have an overall safety strategy before you need it. Now, through an eight-hour (two 4-hour sessions) hands-on seminar, you can learn the personal safety tips and techniques you need to avoid dangerous situations, and avoid becoming a victim. This seminar will emphasize awareness and prevention of criminal confrontation.

    Professional Instructors with over 50 years of combined experience.

    S2 Defense Systems offers a Safety, Security and Self Defense seminar designed for the working professionals and family groups that are concerned about their personal safety. Our personnel are professional instructors with many years of experience in teaching and hands-on security work. Our staff is certified and licensed by national and international organizations and has extensive resumes that can be accessed through links on this website.

    Seminar topics include: home, automobile, phone, technological, travel, and personal security. Seminar participants are presented with a variety of common-sense crime prevention and personal safety strategies and devices they may integrate into their daily lives.

    Topics covered:

  • Home Security - Plant “defensive” shrubbery around your home, especially beneath windows. Bushes with thorns or stiff, spiky leaves are not good hiding places for criminals. When moving into a house or apartment, always change or re-key the locks. Otherwise, the previous resident—and anyone they supplied keys to—has unrestricted access to your home.

  • Phone Security - Consider keeping a separate line or cellular phone as a security device. Taking one phone off the hook renders other units on that line inoperable. Using a separate line or cellular phone in your bedroom is a good precaution.

  • Automobile Security - Use a two-piece key ring with your car keys separate from your other important keys. Give parking valets or mechanics your car keys only. Supplying your entire set of keys creates an opportunity for duplicates to be made. Check your surroundings before getting out of your car. If something or someone strikes you as out of place or threatening, drive away.

  • Personal Safety - Consider taking a self-defense course. A wide variety of courses are offered for self-defense and each should be considered carefully for relevance to your own situation. The S2 Defense Safety, Security and Self Defense seminar provides many useful personal-safety strategies and discusses the pros and cons of other training options.

    These are just a few steps you can take to avoid becoming a victim of violent crime.

    Topics covered include:

  • The Psychology of Criminal Predators: understanding and avoiding violent crime against women.

  • Home Security, Strangers, Visitors: lighting, locks and keys, alarm systems, dogs and their training.

  • Phone Security: protecting private information, answering machines, cellular phones, phone scams.

  • Automobile Security: carjacking, accidents, alarms, parking lots, gas station safety, car as a defensive tool.

  • Self-Defense Physical Training: recognizing dangerous situations, elevators, walking alone, purses, trusting your instincts, what to do if confronted. Participants will learn practical, effective self defense techniques designed to surprise, stun, and disable an attacker, allowing time for escape.

  • Personal Protection Devices: alarms, sprays, stun guns, defensive key chains and other devices.
